Hard drive memory is disappearing

Question: Hard drive memory is disappearing

Forgive me if I've posted this in the wrong forum. Hopefully if I did a moderator will move it to the right place.

I've got a Dell Inspiron running Windows 7. I just opened a my computer window and noticed that I have almost no space left on my C drive. I've got 1.8 GB free of 58.5 GB, down from 2.5 GB left just a few weeks ago. I have no clue how I've chewed up that much hard drive space.

This is my work computer and I don't use it for anything other than internet access and word processing. I run Chrome, and Word Perfect for word processing. The only data intensive folder I have is My Pictures, and it's got about 12.4 GB.

At the same time, it shows I've got 396 GB free of 397 GB on my D drive (local disk). So here are my questions:

1. Does anyone have any idea why I'm losing so much space on my C drive? I don't have a lot of stuff loaded on this computer and certainly my Word Perfect documents aren't gobbling up that much space.

2. Can I move folders into the D drive to start using space there?

Preferred Solution: Hard drive memory is disappearing

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Hard drive memory is disappearing

Have you recently run a disk cleanup tool? There is one built into Windows. Type "Disk Cleanup" into the start button search box.

Windows gradually gets larger to some extent through updates. But mine is under 30 GB and always has been.

How much space do you have allotted to System Restore. That can be reduced to save space if needed.

Do you use hibernation? If not, you can turn it off and save gigabytes equal to the amount of RAM you have.

Are C and D on the same hard drive? If so, you can in effect take space from D and give it to C.

You can also save files to D directly, but that probably would involve some manipulation of your "user" folders.

How large is your C:\users folder?

If possible, post a screen shot of Windows Disk Management.

I've been having a problem like so many others with mysteriously disappearing hard drive space. It has been rather full for most of the time I've had it (i have lots of music and pictures) but it's never been an issue.
Lately though it's been in the red, the least amout of disk space i've had is 4 something GB left of 62.2. I tried deleting programs, deleting restore points, disk cleanups and that sort of thing like everyone else has suggested and it seemed to work for a time, and then I ran a disk defrag and all the sudden more and more memory was disappearing each time i would refresh the window. I stopped the defrag, deleted some more stuff and it seems to be stable at 7.52. I was wondering what exactly I can get rid of to get more memeory (I am not very computer illiterate and am afraid of deleting files and programs I need...) and was wondering why in general my memory was filling each time i would refresh the page.
It's a dell inspiron 1525 with vista home basic if that helps.

Thanks so much.

I hope someone is able to help me with this. I posted on the HiJackThis help forum almost two weeks ago but haven't had a response and I'm running out of memory options. For some reason the memory on my hard drive is quickly disappearing. Every time I turn on the computer I am losing on average 75 to 100 MB. I have purchased an external harddrive and have been removing photos and other large files while I have tried to discover the problem, but I'm running out of things to remove.

I have tried clearing the browsing history, temp files, etc from Internet Explorer every day so it is not that. I have searched for extra large files that are not recognized but cannot find any. I have run Adware, Spybot, AVG, and a Pandascan and have not had any luck there either. I have run HiJackThis and the log is below as well as the Pandascan log.

I'm thinking it is some sort of runaway program or unknown cache or something like that.

Thank you in advance for any help!

Peter at the XP Support Forum suggested I contact you. Something is eating my C Drive! I am running XP Pro on a Gateway 450 Laptop. Last week, my memory was down to 1%. I ran Zone Alarm's virus and spyware scans which resulted in the removal of an IE plugin. My free memory was instantly back to where it should be: 15 GB of 30 GB, which allowed me room to defrag my disk. Since then, it has been on a steady decline, but I have not installed or created anything that would result in such a memory reduction. Each time I check the properties of my C Drive, the free memory is substantially less. I am now down to about 1.5 GB. I have followed all of the steps listed in your announcements. This problem seemed to start when I replaced Norton Security (due to an apparent conflict with the Windows Firewall) with Zone Alarm because I was having Internet connection (cable modem with wireless) problems.

Hi and welcome to TSF

It sounds as if the AV programs might be clearing the bulk of infection but perhaps not every trace and so it starts chomping away again during the 'wee small hours'.

I would suggest having a read here* and try some of the suggestions and maybe do a post on the HJT board and get the view of one of the security techs.

Hi guys, new to posting but I felt I had to try, giving this problem is driving me up the wall and I don't have the technical expertise to work it out for myself.

I keep getting the, dun dun duuuum, ahem, blue screen 'o death, the physical memory dump. Now it does happen a lot more during gaming, but as I've just found to my frustration, not always. Just crashed while I was on msn with a friend running nothing else.

When the comp restarts I do notice in the bios that (on the first screen) my two hard drives sometimes don't show up. If that happens I have to go into the setup and reassert the Master over the Slave as the first drive. If I don't the bios can go to the next screen and stop dead with a "disk error, do not pass go, do not collect £200" and I have to restart Now, like I say, I figure that might be something to do with it, but I'm just not that hot on computers.

If there's more information I can provide to help let me know where to find it and I'll grab it, I'd really reeeeaally appreciate any advice, but if it were in small easy to understand non-technically advancde bits, That's be even better!

Cheers in advance!

First, sorry if I'm a little slow with some of this as I'm moderate with my computer knowledge.

Earlier today I had 517 gb of memory available in the C drive. I restarted my computer earlier today and once it restarted I saw I was down to 1.84 gb. I ran crap cleaner already and did a quick scan with malwarebytes but no answers.

I also noticed a new file listed named c:\END. When you open this with notepad it says "conduitok"

There also seems to be ads and a new toolbar listed in IE. Any ideas how to find out what the heck is going on here?

About 2 months ago it was called to my attention by a friend that I had very little memory left on my C:drive (30Mb out of 38Gb). I assumed it was because of photos and other such files and either removed them to the D: drive or to my external hard drive. I did get back 3Gb of memory and considered myself "safe".
Recently though, and for no reason at all, I have been losing memory again. No matter what I take out, how many malware sweeps or defragmentations I go through, I only manage to go from 20Mb to about 60 and back again. I've even been down to 0Mb....
I haven't installed any new software, other than the one from my webcam (and I think I was already having some problems by then).

I went through the Read & Run Me procedures hoping that would be enough, unfortunately it wasn't. It did find some malware though, so I know something good came out of it .

I believe I have some sort of malware, because otherwise I don't understand how memory would just disappear on its own....

I use Windows XP Service Pack 2. My computer is an Acer Aspires 9104WLMI.

I have attached the logs for SAS, Combofix and MBAM as per the instructions in R&RM.

If anyone can guess at what the problem might I'll be very thankful for your help.


Answer:Memory disappearing on its own from my C: drive....malware?????

Welcome to Major Geeks!

First just and FYI for you. It is not "memory" space it is hard disk drive space or storage space. Memory is RAM ( Random Access Memory ) which the programs on your PC use to run. Any information in RAM is lost when you turn your PC off. You are probably not losing disk space due to malware. You are probably just noticing loss of space due to System Restore points being created each time you boot your PC. You should consider reducing the amount of disk space being used for System Restore. You can work issues like this in the Software Forum or you can read things like the below:

I due see some questionable items in your ComboFix log that are not related to your disk space problems, but I need the log from MGtools that was requested before I can continue.

When I click on My Computer, only the C drive appears. If I try to run any programs that are installed on the G drive, it says that they cannot be found. The last time this happened, it reappeared after a few days, but this time it has been a couple weeks. Any ideas on why this might have occured or what I can do to fix it?

Help: I installed a second hard drive in my PC a week ago and have transferred My Documents to the new drive. Last night the PC froze and when I rebooted the new drive had disappeared and is not listed under My Computer. I?ve looked in device manager and the drive is listed as working properly, I?ve looked in hard drive management and again it is not listed. I?ve tried system restore with no luck. There is a message that comes up on system restore to the effect that drive G (the new HD) will not be changed after the restore date as the drive has been removed or switched off! It hasn?t been removed so can anyone tell me how to switch it back on again?

Answer:Disappearing Hard Drive

HiFirst thing to do is check that the power and data cables are plugged into the drive then go into the BIOS on boot up and see if it appears, if not then its likely that the HDD has died.Try searching the forum as this is a common problem and there are lots of threads that meay help.

ok so, the last 2 weeks at random intervals. my D (back up) drive has been just disappearing and the only way to get it back is to restart.

the only time you notice is when a file cannot be found or if you look in my computer.

the Device Manager does not show anything either, even after a scan for hardware changes.

its been 100% until now. gladly nothing important runs from that drive but the fact of having to restart every time it occurs does get a little annoying.

Have you tried reseating the drive? Disconnect all cables attached to it, then reconnect them. Also disconnect the SATA cable from the motherboard and reattach it.

I bought a web book direct from elonex. Three weeks later the hard drive disappeared, not reported in bios. I assumed a hard drive failure, called elonex and (to their great credit) with no messing they swapped a new hard drive. Initially all was well and I felt smug about diagnosing the fault, but now the same fault has returned. It is NOT due to overheating, since the HD is not visible even when cold. I'll call elonex again, ultimately its their problem, not mine. But I would be grateful for any ideas.

I think the first thing to do would be to download Western Digital's hard drive diagnostic program, Data lifeguard. That should be able to tell you if the problem is the hard drive or something else. If the drive fails, you can try to RMA it if still under warranty.

I am running win 7, and I am having a possible HD issue. I have 2 drives, 1 with my OS on it, and one with all my programs. The other day I was playing a game and my screen froze. I could still use the mouse and was able to bring up task manager, but it was unable to end the program. I clicked restart and had to click force restart because it couldn't end the program that was running. When it came back up, all my icons were like "broken links". I pulled up my computer to check my drives and only the main OS drive was there. I shut down completely for a minute and start it back up and everything is back to normal, but it does it again about 30 min later. I have attempted to run a check disk on the drive, but it feels partway through it and the drive had disappeared from my drive list. Is this most likely a problem with my drive, or could it be something else?

Answer:disappearing hard drive

Start by unplugging the power supply.
Then disconnect the Second Drive and reconnect it, making sure everything is fully seated.

Restart the system and see if the drive is recognised.

If it is, download the manufactures drive checking software and run a full scan on it.

If it isn't try
1. looking in the Bios to see if the drive is listed.
2. booting a Live version of linux and see if that recognises the drive.
3. Plugging the drive into a different computer or put it into a caddy.

Then report back with what you find

I've installed a second hard drive (internal laptop, Vista x86) and it keeps disappearing...

The drive didn't come with any install software so I used the disk management tool in Vista to format (NTFS) & partition etc. I wasn't sure how to do it that way but I thought I figured it out OK.

It appears to be fine & usable, shows up under "my computer" and I've been able to move data onto it. But for some reason, after the computer's been on for about 24 hours the drive just disappears & becomes inaccessible. If I re-boot it'll become visible again.

This last time, I was listening to music from that drive when the song suddenly started skipping. The drive had disappeared again. It's no longer visible in Disk Management either.

Any ideas?

Answer:Disappearing hard drive

Is the drive secured properly in the laptop- they can come a little loose, if they are not.
I suggest you check the connection, first.
If all is well, then I would download a hard drive utilty for that hard drive, and run its diagnostics, as it may be /becoming faulty- if its new, it can still happen.
I find this one handy on laptops.
I have not tried this in Vista.

This problem began occurring this Sunday and I have no idea how it came about. Last week I used MalwareBytes to remove Trojan.Vundo.H (I don't think that has any special connection with this) and then my comp was as fresh as ever. Now my E drive keeps randomly disappearing/appearing when I start/restart my computer.

The data on it is intact, as when it appears everything works fine on it. I have used System Restore thrice, first two times to Sunday and then I tried to do it to 9th April(as further back as I could go) but it said Sys Restore failed. Each time I restored my system the drive came back. The drive doesn't come back as frequently as when I restart or start the computer instead of using Sys Restore.
Apart from backing up my hard drive(obviously, and what are the best tools for that?), what am I supposed to do to curb this problem? Formatting is a last resort option, I'd like to know if there's anything else that can be done.
Plus, my computer loads slower than before. Before the BIOS choice screen, a cursor freezes up on the screen. Usually it just blinks once and everything happens quick.

Recently something seems to eating up any space on my hard drive. At first I thought I just had too many files but even after deleting the space continues to be eaten in a few minutes. I have searched around and the one solution seems to be regarding restore points but when I type the vssadmin list shadowstorage command into the cmd it comes up with the response that the query could not be found or something along those lines. I also tried to delete the last few restore points via disk cleanup but it didn't free up any hard drive space.

The problem started appearing recently even though ive owned the laptop for a year and its running vista. Any help would be appreciated.

HiHere is my problem. Sometimes my computer is booting up just fine. I am able to go into windows and it runs ok. But another time if I boot up the computer, the Ide master hard drive (windows drive) is not recognised in the bios. Or I can get to windows, but after a period of time my computer will reboot and again the master hard drive is not recognised by the bios. So far the only things I have done to get this back up and running are to push harder on the ide cable connection to the hard drive. I have also purchased a new ide cable, but the same thing happens. I have checked the pins at the back of the hard drive and they appear straight. What do you suggest I do now? Thanks!!

Answer:Hard drive keeps Disappearing

How old is the drive?The controller card on the drive might be going out. It can only be replaced by an identical card and hard drive companies don't just hand these out. I'd back up whatever you need while you can and look at getting a new drive.It could also be a problem with the motherboard. If you have another drive handy, put it in, install Windows, and try it out for a while to see if it works ok. If there are no issues, it's probably the hard drive you have in there now.

I am at my wits end with this hard drive.

I have a Maxtor 300 gig sata HD (not my drives of choice by far) that keeps disappearing.

I have the HD partitioned into two drives, one is 40 gigs I run windows on, the other is the remainder I used for storage. I also have other sata drives (3 others) hooked up to the pc.

Anyway, I've had this setup for about a year or so and had no problems. Recently, I started to get random freezes and from time to time I'll go to access an application or piece of media stored on the second partition and notice a path error. When I open my computer there is no second partition.

I've tried the chkdsk /f option on the second partition on start up and it seems to complete ok. I don't seem to get any errors in the applications or system menu's of eventviewer. I've run a couple of different hard drive diagnostics, like SeaTools and the Maxtor one and neither ever find a problem with the HD.

The only way I can seem to alleviate the problem is by rebooting, upon which the HD is detected again.

I am not sure if this is a failing sata cable or port (by why would the first partition still work?) Problem with the drive itself (again why no problems, unless the freezing is one, with the first partition) or a problem with windows.

When I formatted the drive I did both in NTFS. The drive is only about 2 years old, and doesn't seem to make any of the noises that I have heard previous failing drives make.

Answer:Help with a disappearing hard drive

Sorry, I just found hard drive errors under the system tab in event viewer. I am not sure what the hell I was looking at earlier.
It looks like every time the HD disappears it starts off with a warning like this "An error was detected on device \Device\Harddisk1\D during a paging operation."

Followed by 15-20 errors (the red x kind) where the description is something like this "The driver detected a controller error on \Device\Harddisk1\D."

Followed by a few NTFS warnings to the tune of "{Delayed Write Failed} Windows was unable to save all the data for the file . The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere."

And finally ftdisk error "The system failed to flush data to the transaction log. Corruption may occur."

and then I think that is when the HD is disappearing.

Does this sound like a failing drive issue?

It appears that at the time this occurred I was not even home.


Edit: I think I am suspecting the SATA cables. Even those these are fairly new cables they are pretty cheapo ones. Does this sound like a cable issue?

This problem happened a few times off and on over the last few months. In the past I would put my Windows 7 64bit ultimate boot disk in did repair and everything is fine, but I couldn't figure out the problem.

All 3 of my drives are SATA, a 640GB WD (My boot disk) a 1 TB Hitachi (my back up) and a DVD burner.

Now every day 2-3 times my computer will restart, it will POST, then when it shows drives right after post, it only shows my storage/(crude back up/draganddrop) hard drive and my DVD rom). Now when I put in my Windows 7 disk and try to repair I can do it 1-5 times and usually on one of the restarts my 640GB boot will show up again, my computer will start and no problem. I have never had a "restart"/crash happen while using the computer, typically I will wake up and notice it or like make dinner, so I wonder if it has something to do with going into energy saving mode. I used my computer all day today with no issues, and actually almost ordered an SSD, because if I have to reinstall the OS I am going to use this as an excuse to the significant other to get a nice new Harddrive.

Of course if I can fix the problem I will hold out for Black Friday for my SSD.

Any thoughts are appreciated. I figure I'll have to do a clean install at some point, just not sure if there might be a temporary fix.

Hi all.  I am new here and hope that someone can help me with this problem that has been plagueing me forever.  One of my computers always drops a hard drive.  It is on an ABIT KR7A Raid motherboard.  Now what happens  is after computer has been shut down, upon reboot the secondary slave hard drive is gone.  I have to go into the bios and redetect it, and then it will be back and working fine until the computer is shut down again.  Now what I've done to try to fix this so far:2 hard drives on one IDE cable.2 CD ROM/burner on another IDE cable.1.  Changed Ide Cable.  Works fine for about a week and then it starts dropping out again.    curious.2.  Upgraded the bios.  works fine for about a week and then starts dropping out again.  curious again.3.  Installed new Via drivers.  Worked fine for about a month or so, then started dropping out again.4.  Swapped the Hard drives and CD ROM/burner on the motherboard IDE ports.  Worked fine for a while.Now it's to the point that even going into the bios and redetecting the hard drive doesn't bring it back.  It shows up as a Maxtor, but instead of showing the number it shows  Maxtor  DRACO.At my wits end, I popped out the CMOS battery and it came back fine.  Then I rebooted the computer and it disappeared again without being able to fix this by going into the bios.  Anyone have ANY ideas on what this may be.  It is dri...

I posted my problem on another forum I go to, but since it's not a tech forum (the specific tech sub-forum there hadn't seen a new post in four months), I haven't received much help, so I figured I should go where hopefully someone could help me out. I certainly wish I could just Google this and find a solution, but as I'm sure you're all aware, everyone's problem is different and there's no one easy solution for everything, so, I'll try to be as detailed as possible with everything going on with me and maybe someone will be able to come up with some suggestions.

I use an external hard drive for most of my file storage. About a week and a half ago, I noticed that it would 'disappear'. Meaning that I wouldn't really be doing anything and suddenly it would disappear, it wouldn't be visible in Windows Explorer, any files (i.e. movies) that were open on it would cease to work, and so on. It was really strange and unexplained, but I would just power the drive off and then on again and it would reappear and everything would be fine.

Then I noticed it starting to happen more often with more direct interaction with me. I'd be going through folders looking for files or whatever in Explorer when there'd be a period of lag after clicking on a folder, and when the lag finally stopped, the drive would have disappeared (during the lag, I also at times attempted to close the program with Windows Task Manager, which, whi...

Hello everyone, pretty new to this site and have a slight problem and was not able to find any answers that fixed my problem. I bought this computer about 2 months ago used and noticed recently that my 300 gig hard drive has magically disappeared down to 36ish gigs throughout the last month or so. I know I have not downloaded anything that much space demanding, so it must be a virus of some sort.
Here's some pictures if they help any:

Answer:Disappearing hard drive space.

Hello and Welcome
You can download WinDirStat to see where and what is taking up space on your hard drive. To get rid of the temp files first type Run in the Search Box. Click it and in the Run Box type %temp%. This will open up a window of your temp directory. You can safely delete files and folders in this directory. If you have more than one account on the computer, do this for each account.

I have been having an issue with hard drive space disappearing. I actually got down to 0 hard drive space. My husband took our laptop into work, as I thought it must be a virus. According to his IT dept. it was not a virus. The IT guys were able to get 67GB of hard drive space back, but within the last 10 days I have gone down to 54.9 GB. We haven't downloaded anything so I know something or some process is eating up the hard drive space.

I noticed in a previous thread someone else was having the same issue and they were told to turn off disk defrag scheduler. Funny because I did have disk defrag scheduled to run every wednesday pm. All day on Wednesday I had 61.6 GB and on Thursday morning I had 56 GB. After reading about disk defrag I turned it off, ran CCcleaner, windirstat and anti-malware. I believe disk defrag is the problem but I can't find any files to delete after running the windirstat. I notice in the app it has a Clean Up tab. Is there something I need to do??? How can I get my hard drive space back?

Answer:Disappearing Hard Drive space

I would go to computer right click C: and click disc cleanup when finished click more options and delete old restore points and shadow copies that should find some space.

HiI am using a Dell Inspiron 6400 laptop and the internal hard drive space is constantly disappearing. Today I turned it on to find that 12 gigs of space had been filled for no reason, I got rid of a load of data and this morning I had over 7gigs free. Since then I have been doing some word processing and when I looked just now it has dropped down to 3.5 gigs (I haven't downloaded a single thing). It has been doing this on and off for a while now but before today it hadn't occurred for a few weeks.Please help because I am worried that it will drop down to 0 again and I will be stuffed!Thankyou for your time

Thanks for putting up the feedback. I own a X20 and a T42 before, currently I own a R61i which is anout one week old. However, i do have this problem when I start using the system, it eats up all my hard disk space even though I only install the basic Microsoft Office and nothing else. Apparently, this problem also happens to my Lenovo 3000 N100 which I bought 6 months ago. I have no choiuce but to down grade to XP professional and it is working fine now. I send back the machine to the service centre and they too are puzzled and does not know what is the cause of the problem except to re-format and re-install my system, I just got my system back today and hopefully I can get it up and running wihout the same problem appearing. Can anyone advise if there is a compatibility problem with Vista Business and Lenovo system. Apparently, there seem to be a bug to fix up.Moderator edit: moved from Introduction threadMessage Edited by carbon_unit on 12-04-2007 06:03 AMMessage Edited by Tim_Lenovo on 12-04-2007 09:58 AM

Answer:R61: Disappearing hard drive space

simonkohWelcome to the forum What you have posted leads me to ask one or two questions; have you noticed that your hard disk space is being eaten up on the R61i? Your downgrade to XP on the N100, did you do it manually, or did you have recovery cds for XP?My reason for asking; there is a pre-installed Lenovo Utility called "Rescue and Recovery". This is a back-up software which can be used to recover your system if windows crashes. There is however one feature which has been the cause of some frustration; as default it is set to back-up the system every Wednesday at 2pm, (I think). What happens is that some people don't notice this and after a while their free space has disappeared, the solution is to either turn off the automatic back-up so it doesn't use anymore space, or delete the already made back-ups and start over.

I have a WD "My Passport" external USB drive that I connect as a backup for my system. The problem I'm having is that the drive keeps disappearing randomly. Sometimes I have to unplug it and re-plug it in 3 or 4 times before my computer recognizes it. I've tried several USB ports, and still have the same problem. The hard drive itself doesn't have a shut off switch, so it takes its cues from the computer power management system. When I plug the device in, sometimes the drive doesn't mount, but the power light on the drive will turn on.

Why is it randomly turning on and off? And why do I sometimes have to plug and unplug the device several times before it correctly recognizes it as a hard drive (with all its data in tact)?

Though my other USB devices do not randomly disappear while running, they often take three or four plug ins and plug outs before they're recognized in the first place.

How can I fix this, as I need a reliable backup drive always hooked up.

Answer:USB hard drive keeps disconnecting/disappearing

In power management (Control Panel) go into the advanced details of your power scheme and alter the settings which power-down your hard drives and USB interfacing to save energy - this will mean your device is kept running and is perma-detectable.

Hi, lately I have been experiencing some wierd problems with my computer.

I can't somehow boot into windows 2000 from my Master hard drive.

I think the problem stemmed from me downloading this game program in exe format (I know, my fault for running it).

My computer seemed fine for the first few days, as I never shut down my computer. But when I reboot my computer, one of my partitioned hard drives just seemed to disappear.

Then when I reboot again, the computer logged me into a blue background with white text saying

a corrupt file with Wininet.dlll, that it had a bad image and the checkSum was corrupt.

Can someone help me out? I would be greatly appreciated.

Hello, all.

I've just now installed a secondary Hard Drive onto my machine. I formatted it to be NSTC (I'm not sure that's the abbreviation, but it's the one windows xp uses [at least by default]). The first time I launched windows after that I got a message that said "New Found hardware [hd name here]" and after a few seconds the drive appeared under "my computer". I tryed to copy over a ton of files, and I realized that just wasn't going to work, so I hit quit, and after a few seconds it stopped trying to copy, and an error message that said something about my hard drive lagging (I can't be more specific as it came out of the corner of the screen, and disappeared fast). I then went to check, and I saw that the drive was no longer listed. I tried restarting, and still, nothing. If it matters my main hard drive (the one windows is installed on) is SATA, and this one is IDE-ATA (The cable goes from the CD/DVD burner to the secondary HD, and then to the computer).

If someone could give me advice on how to get the hard drive listed again, on a management software, or anything else on this matter it'd be greatly appreciated.

(Windows XP SP2)

Answer:[SOLVED] Disappearing Hard Drive!

Hi there and welcome to TSF.
You're close, it's actually NTFS . First, how many IDE slots do you have because it's not a good idea to have your hard drive on the same cable as your CD/DVD burner. If you've only the one, as is often the case with SATA motherboards, then you have no alternative, but I would put the hard drive at the end of the cable, not in the middle. The first thing to do is to see if your machine recognises all your drives in BIOS. When the machine boots up, press F2 or DEL repeatedly, depending on your machine. This will take you into your BIOS. Find the page that lists your devices. In Phoenix Award BIOS this will be under Standard CMOS Features. I'm not sure about AMI BIOS. If the second hard drive isn't shown, make sure that all your connections are secure. If it is there, exit from BIOS and reboot. When in Windows, go to your Device Manager by clicking Start then right click My computer and selct properties. Click on the Hardware tab then select Device Manger. Check that the drive is shown there under Hard Drives.
Please report back what you find.

I followed this forum's guide to reinstalling XP on a computer with Vista already installed :

XP installed fine and using the new Bootloader program BootVis worked great. Booting and selecting an O/S is not a problem. However, after loading XP and getting all the updates my 125GB hard now shows only 4GB free on it. I know there isn't just 4 GB of free space left and by my calculations there should be around 100GB of space still on it.

Does anyone know why the free space is so low? And how can I get this free space back?

I upgraded from Win XP to Windows 7 64 bit about a month ago (I did a clean install as I've always had issues with in place upgrades). My machine has four hard drives total, two internal SATA drives, and two external USB drives. For some reason my secondary internal drive, a WD 500 GB SATA drive (nothing fancy), keeps disappearing randomly while windows is running. This started about a week ago, it ran ok for the first 2 weeks or so.

The drive comes back fine and dandy if I completely shut down the machine and then boot it back up. The drive stays until some random moment when Windows doesn't see it anymore. Now, if I do a simple Restart the drive doesn't show up, ONLY after I shut down completely, and push the power button back on, does this work. There is nothing in the System logs, no error messages, nothing, it just vanishes and is completely random.

Please help as I REALLY don't want to go back to XP but I've checked the hard drive with windows and other programs and it never reports any problems, the BIOS detects no problems, even Windows recognizes it for a while, then nothing...

Answer:Internal hard drive keeps disappearing

Hello zdawg, and welcome to Seven Forums.

I use to have this happen to one of my internal SATA HDD drives. It turned out that updating my AHCI SATA driver for my motherboard to the latest version resolved the issue for me. You might also update the motherboard chipset driver to the latest version as well to be safe.

Hope this helps,

I am posting here because after numerous actions on my part I have decided that this is a Vista issue.

I am very concious of my hard drive space ( I am a wedding photographer) and as a norm transfer files off my SD cards into my PC using windows explorer and just drag and drop them into the appropriate folder.

About 2 weeks ago I noticed that suddenly I seemed to have 10gigs less HD space than ther day before, ok maybe it's my imagination. Then about 10 days ago I went from having 90+ gigs free to having 28 gigs free. After re-running Grissoft anti-virus and disck clean up and a bunch of other deleting I was back up to 46 gigs free. Well life got in the way and I just had to go on then today I noticed that I have 12 gigs free. I have down-loaded nothig that could account for more than1-2 gigs of space.

In an effort to discover the problem, I have run...

J-Disk Report shows that I'm only using 93 Gigs of space (which is what it should be) of my total 225 gigs
HijackThis, which shows nothing out of the ordinary
AVG Gris-soft Antivirus, I'm Clean
AVG Gris-soft Anti-Spyware, I'm clean
AVG Gris-soft Anti-Rootkit, I'm clean
Spybott search and destroy, I'm Clean
Lavasoft Adaware, I'm Clean
Ccleaner, I'm Clean

AHHH! I'm lost.

Given what J-disk report is showing, I'm inclined to think that Vista is loosing it's mind.

I will be grateful for any help requiring any level of expertise (hubby is a programmer).

Thank you,

Hey, im a bit new to all of this so please bear with me...

Recently i've noticed that the space on my local hard drive has been slowly decreasing for no apparent reason, even when there are no programs running.

I literally sat down and continued to click on it, only to find the space decreasing by 1mb every now and then.

I downloaded and ran combofix because a friend of mine advised me to, and the guide to running combofix directed me here as one of the places i should come to once i have the log.

i've run combofix a number of times, as it has so far managed to clear up all the space that this unknown 'thing' has gobbled up, although now im getting slightly fed up at having to deal with this, so id much rather seek out the root of the problem.

i will gladly post the log i got from the last time i ran combofix, but i dont want to post it straight off with my first post because its against the rules to post one without it bein requested... so i shall just sit here eagerly awaiting any feedback.

If theres anything i need to do prior to receiving assistance, id happily take the necessary steps!

Good afternoon I'd really appreciate some help with my computer. The day before yesterday I noticed that some of my folders had disappeared from my hard drive. I run Trend Micro Internet Security 2007 and have conducted a couple of scan with no viruses found.

To test the system I created a new file folder on my C drive via file explorer and moved some data into it. When I reboot my computer the new folder shows up in file explorer briefly and then appears to be deleted. I checked the amount of used space prior to adding the test folder and after I added it. I also check the used space after the test folder was deleted and it looks like the folder is removed completely as the used space drops back to the original value before the test folder was added.

I don't download cracked programs but I did recently download a P2P movie with utorrent. I've learned my lesson after reading your forums and have deleted utorrent from my system.

I'm not sure what to do next.

Does anyone know what could cause a 80Gig hard drive to keep disappearing in windows? I've changed cables etc but nothing i try seems to work. After formatting my hard drive ages ago it reappearded for a bit, but then started to disappear, then come back, then disappear. A friend advised me to install service pack 2 for xp, this didn't solve the problem either. I tried unplugging all of the cables then reconnecting them, after doing so my d drive appeared for a few weeks, but started disappearing again intermittently, now it has disappeared again totally. Before the reformat the e drive was having the same problem as well as the d drive. My e drive is my cd writer. I'm presuming it's only a matter of time before this starts disappearing again. D drive has dissapeared completley now in explorer. Could this mean I have a dodgy mobo? Any solutions?

I have a hard drive problem that really puzzled me. I have a 120GB HD from my old computer with window XP on it. It was partitioned in 2 drives; 1 drive with 40 GB with window XP system, the other drives with 80 GB for data file only.
I recently bought a new HP desktop with window 7. I pulled the HD from the old computer and put it into this new computer as a second HD. The new HP computer can recognize the second HD. However, it shows that this hard drive only have one partition that has all 120 GB on it. The only files I can see are the ones on the old system partition. I could not see any data files that were on the second data partition. I already recycled my old XP computer. I still have some recent data files on this hard drive that I have not backed up yet. I would really appreciate if there is any way to find these data files on this HD. I already checked disk management and it only shows one big partition for this HD (no separate data partition).

A week ago, my boyfriends computer stopped letting the virus scan run, due to not enough space. He picked up an external harddrive (1t), and I transfered all of his video files to the external drive for him on Friday night, freeing up around 16g of space.

As of last night, he had less than 2g of space on the harddrive! I transfered all of his photos to the external drive (leaving him with over 8g of space available), we went out for awhile, and it shrunk again.

I've already deleted all of the old restore points, Symantec hasn't found anything (he has endpoint protection), and Malwarebytes hasn't found anything either.

I'm stumped! Any suggestions on what could be eating the harddrive space?

So a little less than a year ago I bought an IBM Thinkpad T60 with Windows XP and a 120 GB hard drive. When my laptop first arrived, after being formatted, there were 106 GB free for me to work with. I don't quite remember exactly when I noticed, but within a month or two I realized that I was already down to my last 25 GB or so of free space. Now, I have some software on my computer and about 6 GB of music, but I downloaded TreeSize Free to analyze the distribution of my files and according to the results I only have 19 GB of files (i've included the print screen image of the results below).

When the computer refuses to boot into Windows on going into the BIOS only the 'data ' SATA drive is shown- all the other three SATA ports are empty. However the weird thing is, when I then disconnect the SATA drive the bootable drive then boots into Windows OK. I have tried swapping the cables and drive port positions around but this doesn't appear to make any difference. When I later put the data drive back in everything is OK.....for a few days..... or weeks... then the problem recurs.
Any pointers to finding the cause please?

Hey, i've got an 80 gig IDE HDD which i use as my main windows drive and it works great. No problems with it. I've also got a 120 gig SATA drive which I use as a backup drive. The SATA drive shows up in the Safely Remove Hardware window which i've done a little research on and realised that that is perfectly normal.

The problem i'm having is that any random amount of time after i've restarted my computer, the SATA drive will just disappear and I get that little ding sound letting me know that something has been "safely removed" i guess. (That same sound you get when you unplug your ipod) It's doing this completely on it's own though and at completely random times. Sometimes it will be 5 minutes after I restart, sometimes it will be 2 days after I restart. I'm pretty sure it's not a cable problem because as soon as I restart my computer the drive shows up as normal again. Everything functions flawlessly until the hard drive "removes" itself.

I found a value I could add to my registry that would make my hard drive unremovable and it did remove the "safely remove hard drive" icon in my system tray but the hard drive still disappeared after a few hours of use. I've been unable to find any specific pattern when it removes itself. Any tips would be appreciated. I've got a sneaking suspicion that the drive may be starting to go. Any way I can check for sure? Thanks

Answer:Hard drive randomly disappearing

Is this an internal or external drive?

Did you try replacing the cable?

Hello So my hard drive was originally like 200 GB or something, but of course the operating system took up about 25 gigs, so it says it's out of 174 GB. It currently says I have 102 GB free. However, I added up everything on my computer, and it says I've used only 45 gigs. That means I should have 129 gigs left. I know all about the system restore thing and I've deleted "all but the most recent" like 80 times in the past day lol, but it doesn't do anything. I've run CC Cleaner and Defraggler and everything. So I'm wondering where the 27 or so gigs I should have is and what I can do to get them back. Thanks.

Answer:Hard drive space disappearing

Hello Zigeroid, and welcome to Vista Forums.

Your missing hard drive space may be from this:

Here's a formula to convert retail size to actual size. This assumes that the manufacturer is using 1GB = 1,000,000,000 bytes (instead of 1GB = 1,073,741,824 bytes as they should). This formula is an approximation. Many times they will round the drive size somewhat, but this gives you a rough idea of the real world space.


1 B(bin)= 1B(dec)
1 kB(bin)= 0.97656 kB(dec)
1 MB(bin)= 0.953674316 MB(dec)
1 GB(bin)= 0.9313226 GB(dec)
1 TB(bin)= 0.909497 TB(dec)
For GB(binary), multiply GB(decimal) by 0.9313226

Since with 200 GB, the units are still in GB, it can be expressed as 200 x 1 GB.
200 x 1 GB(bin)= 200 x 0.9313226 GB(dec)= 186.26 GB(dec)
These are rounded to the nearest gigabyte for retail size to actual size.

36gb = 33.5gb40gb = 37gb60gb = 55gb74gb = 69gb80gb = 74gb100gb = 93gb120gb = 112gb160gb = 149gb200gb = 186gb 250gb = 233gb300gb = 279gb350gb = 326gb400gb = 372gb500gb = 465gbHope this helps,

Hi Guys

My husbands laptop has a harddrive split into a C Drive currently running at 44GB free of 149GB...all cool.

However, his D Drive, which he doesnt use for any personal files, in fact he hardly has any files or photos etc. It used to be fairly empty, and now it has been in the red for a while and now is is showing 25MB Free of 137GB!!!confused:confused

I have studied his D Drive, as has he and we cant find any BIG files to delete.

Where do we start in looking for the monster that is taking over his

He is running Vista Home Premium.

Any help much appreciated!!

Thanks in advance

Answer:Disappearing portable hard drive

Typically...when a drive has a problem.

Since it's an external drive, it could the enclosure the drive is could be the actual hard drive itself.

My suggestion would be to remove the drive from enclosure...connect it directly to a working system...and see if the system picks it up properly.

If it does, then I would suggest moving all files from the drive immediately...and then running the appropriate hard drive manufacturer's diagnostic (long test, not short) on it.

If My Computer does not reflect the drive, but Disk Management reflects as either an empty volume, a RAW volume, or an unknown file system...then your best effort will be to try data recovery software.

I have a Toshiba Satellite laptop 64 bit, bought last year in March, using Windows 8.1, AMD Dual processor with a CD/DVD RW drive.  I've had many problems with accessing Windows, dropped partitions, unable to boot, corrupt hard drives, but NEVER in the history of using modern PC's (7 years) has this happened to me.I've lost my hard drive, literally!  When booting it says "No Bootable Device".  I cannot access it using Linux, either.  My computer does not know it's there.  Do  you know what happened?  Can I get it back?  I had it on a surge protector, so I don't know what happened.  Any information would be helpful.  Also, can I use some sort of device to put the resident hard drive into and at least retrieve the information off of it?  I have experience with PC hard drives, but not laptops.Thank you for any help you may be able to assist me with.

Answer:The Case of the Disappearing Hard Drive

The hard drive is likely bad. If the BIOS doesnt detect it then its failed to the point that you would probably have to send it out to recover data from it if there is any critical data that you need. This can be expensive.If you didnt create a recovery disc or USB flash drive set for this laptop you will probably have to contact the manufacturer to get a copy of the system recovery media. This is probably going to come at a cost of around $35 or so.You will also have to install a new hard drive into the computer and this also comes at a cost. I would go with a SSD instead of a HDD ( solid state drive vs a regular hard drive ) if you can afford to do so and dont mind working with lesser space to store data. SSD's hold up much better in laptops that are subject to getting bumped when moved around or used.There are methods to try to get data back from a failed hard drive such as putting the drive into the freezer and then installing it and then trying to access the drive, but the problem here is that your computer is a laptop and the drive might sweat when the cold drive is installed into the laptop and the drives sweat could damage the motherboard. If it was a desktop computer the risk of humidity damage to neighboring parts is lesser and so this is a common trial to get data back in desktops, but i dont suggest it with a laptop.

I built this computer my self about 2 years ago. I had a 20gb HDD that i use to have my OS on but 20gb is not enough so i installed a 160gb HDD as well. Both are compatible with each and were working with no problems until last Wednesday. First my video card went so i took it to a shop and the put the Gforce 200 series in. I got it home, worked fine. I installed a game off of steam onto my E: (160gb) and tried to run it. It worked for a while then nothing happened everything froze so i restarted my computer. Since then my E: keeps on disappearing and reappearing. I have multiple programs on it nut have only tried to run steam. It runs but after about 10mins into it I either get a message in the notification area saying Error saving smf% and then everything on that drive that was running would shut down and the HDD will disappear or the HDD will just dissapear without any warnings or notifications. After rebooting a couple of time it shows up but it asks to reformat when i try to enter. If i restart a couple more time it comes up fine but if i try to open anything up it says its corrupt. If i reboot aftre that everytthing works well and good for 10mins again then i have to reboot half a dozen times. I have tried several things such as uninstall/reinstall the drive, updating it and rolling it back.

Is there a way to fix it? Without re-formatting?

Alright so ive looked through here and i cant find any body that is quite having the same problem as me... I have two hard drives my C: and D: both are about 142G capacity. On my C: drive i have about 111.5 gigs used up from computer games and the sort, but all of a sudden 2-3 days ago my computer has been telling me im running low and disk space, so i did a bunch of disk clean ups, defragmented my drives even deleted all restore points except my last two. I deleted all shadow points and ran multiple different virus scans and malware scans. So far nothing has come up as the culprit as a virus. I have also looked up in my drive all the files and it still adds up to be about 111.5 gigs give or take a gigabyte. Then i installed JDiskReport and IT says i have with everything on C: drive i am only using 116.7G... I do not know where this extra 30 ish gigabytes have come from but they were sudden and the only way i can keep my computer running is by deleting a game at a time to free up some space before it dissappears again... I am doing this on my laptop, and the problem is on my desktop. Its windows 7 4 Gigs of DDR2 memory and this is the only problem that i actually have had with this computer since i have gotten it in 2009. Also my D: drive is exactly the same as before.

Running Laptop with XP. "My Computer" shows a local disk of size 69.4 GB. However, if you double click it and select all, and check the properties, there is only 26.6 GB of files. This is done while able to see hidden files and folders, as well as protected operating system files. The only slight connection I have made so far was when I had utorrent remove the torrent and data of a few files. The files were removed, but no disk space was gained. Is there something wrong with utorrent or is it a Windows issue, maybe something else entirely. I wanted to see what might be causing it before I reinstalled the OS.

Answer:Disappearing Hard Drive Space

I don't think it's utorrent anymore. The laptop seems to have gotten the space that was deleted from it. the freespace increased from less than a gig to 10 gigs. There's still about 30 to 40 GB that are still unaccounted for.

Last month, I built my first DIY rig (yay ) and it's been running as smooth as butter, up until a week ago. I originally only had the HDD, using it for the OS and storage. Two weeks ago I added in an SSD, using it as my OS drive and putting all my games and media files on the HDD.

Last week, I noticed that my media drive dropped out of windows. Checked My Computer, not there. Neither in the Device Manager. So I reboot into the BIOS, and it's there, so I load windows and it happened again after a few hours.

This has been happening on and off and very randomly since. I've already configured my power settings to turn off drive idle, replaced the SATA cable, switched SATA ports, tried the old cable in another port, re-seating the power cable, using a different power cable (modular PSU), all does nothing. It continues to randomly happen. Even as I type, the drive is non-existent to my OS.

At work I'm using a Dell Dimension 3000 system/ WIN XP Pro SP2. Just a few days ago I received a "low disk space" window showing I have less than 10 MB of HD space on a 35 GB HD. That's IMPOSSIBLE. I haven't used THAT much space. So, I figured I must have a computer virus but I don't know where or how to search to resolve this issue. I've uninstalled programs I don't use much, cleaned out my Outlook mailbox, and deleted temp files. A few weeks ago my computer started runnning real slow then I received a black screen stating "windows_root\system32\hal.dll missing or corrupt: Please re-install a copy of the above file." I did an Internet search and resolved that problem by rebuilding the boot.ini file. The PC worked fine for a few days then my HD space started to disappear. I can't run a virus scan because I don't have enough free space. Now I'm showing less than 10 MB of free space. I'm at a loss. Any suggestions?

I have a 3yr old Lenovo laptop running XP pro with a 160gb hard drive.Recently the machine has been running relatively slowly, and when I checked the disk space in my Computer it said of the 105gb(?) capacity, there was 8gb spare. I did a disk cleanup, deleted all old restore points, and degfragged it without gaining hardly anything, and then 2 days later the space is down to 2gb. In that time we?ve only created a couple of small word files, and not downloaded anything etc.I?ve searched for large files and done another disk cleanup, but whats puzzling me is that when I do ?properties? on each folder on the C drive I get the following:SW tools = 2.7gbWindows = 7.6gbMy docs = 30gbProgram files 6.3gbThere are a couple of other folders with only a few Mb in them, and when you add the whole lot together, the total amount of space used only adds up to approx 49-50gb. Where has all the other space gone??I accept that the pc does have quite a few programs installed, and the My documents folder is relatively large, however why doesn?t the sum of all the folders listed as being on the C drive add up to the 100gb of space that has supposedly being used up?

1. stripped virtually everything optional off the computer
2. run virus and trojan checkers
3. run disk cleanup and cclean to reclaim space and remove restore points
4. set only a single restore point
5. set the shadow copy to only 500 mb
6. searched files, including hidden files, and can't find anything unusually large

This is the one I can't solve.............


I just upgraded and bought a new computer running at 2.6 GHz Intel. I decided to go the brand name route rather then building a system, because of the bundled package and the price factor. So to make it short, I just picked up a Sony VAIO PCV-RS320 Desktop (system profile is at the end)


Now this is a new system, which I only bought a few days ago, so I haven’t really played around with the configuration of the system much, nor have I added any software. But what I have done is added a new hard drive ( Maxtor 80 gig – 5400 rpm) to the system from my old computer into the new. After the install the computer and all the programs contained in it operated just fine. In fact, it had no problem recognizing the hard drive installed, and I was able to both add and search all the information stored on the drive.

Now, The problem occurs when the computer is left idle, and it enters hibernation mode. When the system comes out of Hibernation mode, the installed Hard drive and all its components don’t appear.

At first I thought it might be a loose wire or cable, miss during the install process, but this wasn’t the reason. I also did a hardware search, and did a windows update on the computer, still no Hard Drive.

I lose free space steadily (I've seen as high as 40MB lost per minute), from startup until there is no space left. If i restart my computer, the free space comes back, but still begins to decline again.

I first noticed this a week and a half ago, and given the rate at which my HDD space disappears, the problem has probably been on my comp since about two-three weeks ago. In that time frame I have installed IE8 Beta, a program called WebDrive (now removed), updates for Motorola Phone Tools, and a driver for my wireless adapter (the last two came after noticing the initial problem, so they should have no effect).

Answer:Hard Drive Space Disappearing

Not sure if there's anything in the HijackThis log that's worth removing, but I managed to fix the hard drive space loss by removing SP3. I now have to repair windows to fix some components, but otherwise it's fine. Thank you for the help.

Good evening I'd really appreciate some help with my computer. Yesterday I noticed that some of my folders had disappeared from my hard drive. I run Trend Micro Internet Security 2007 and have conducted a couple of scan with no viruses found.

To test the system I created a new file folder on my C drive via file explore and moved some data into it. When I reboot my computer the new folder shows up in file explorer briefly and then appears to be deleted. I checked the amount of used space prior to adding the test folder and after I added it. I also check the used space after the test folder was deleted and it looks like the folder is removed completely as the used space drops back to the original value before the test folder was added.

I'm not sure what to do next. I ran HijackThis as a diagnostic.

Hello Timneedshelp

I`m sorry, but we cannot help you with malware removal in this forum.

Please read ?Virus/Trojan/Spyware Removal Help ? and follow the instructions very carefully; then, post all the requested logs and information in the Virus Help Forum
If you cannot complete any step, just miss it out and do what you can, but be sure to include this information in your post.
Please ensure that you create a new thread in the Virus Help Forum; not back here in this one.

Please be patient, as the Security Team Analysts are usually very busy; one of them will answer your request as soon as they can.

If the problem persists after that I think you need to check the hard drive
First, back up all your important files

Start/Run and type in

When the command window opens at the prompt type
chkdsk /r (there is a space before /)

Reboot and chkdsk will run.

Be prepared for this to take hours if chkdsk actually finds any problems and tries to fix them.

Hi all,

I'm trying to install a second hard drive for additional storage. The HDD is recognized in bios but is not showing up in windows after every reboot. The only way to make it appear is to go into device manager and scan for hardware changes. The drive will appear and be accessible for a while and then disappear again randomly. So, I will have to scan for hardware changes again to make it show up. Anyone have any ideas on what do try? I appreciate any and all help as this is driving me nuts!

Things I have already tried:
1. Checked for loose connections
2. Replaced SATA connector and changed power connector
3. Swapped SATA port with my primary drive (Primary drive still recognized and boots fine)
4. Removed optical drives to reduce load on PSU
5. Updated BIOS and drivers
6. RMA the HDD

Answer:Hard drive disappearing randomly

you need to initialize the drive and format it first before windows can use or even "see" drive

I do not know what o.s. you have, but this should be close for all...
go into the Control Panel, select Administrative Tools, select Computer Management, look for Disk Management, and click on that. You should see your drive in the Disk Management box, Select the option to initialize and then format it. When you go to My Computer, your drive should show up

Hi, I am running Windows 7 on an HP laptop that is over 4 years old. Over the last few months, Explorer shows that the hard drive fills up at approximately 1-3GB per day, even when I know I am not downloading anything. I run CCCleaner and remove all unnecessary files, use Avast Free and do security checks. I also run WinDirStat that shows my hard drive is only using 180GB (this appears to be accurate) when Explorer shows that it is +220GB full. Is this a malware fault or a sign of failing hardware?

Hi Geosteff I helped someone with the same issue yesterday and it pretty much looks like you are having the same issue as him. Click on your Start Menu, then right-click on Computer and select Properties. From there, click on Advanced System Settings in the left pane. Go to the System Protection tab and click on the Modify button. What is the maximum usaged defined for the System Restore, and what is it's actual usage?

not completely sure how to explain this, but my hard drive is losing space at the rate of about 1 MB per second. if you click on it, it'll show you how much free space is there, and if you refresh the display, it'll go down at regular intervals. after reaching 16 KB or so, it either goes back up or simply stops there. i haven't notice anything bad actually happening, it's just very disconcerting.

i have two partitions, c: and f:; the c: partition has windows XP on it and that's the one to which the problem is occuring. the f: partition is fine.

edit: oh yeah, running CHKDSK turns up 40,000+ "invalid security identifiers" and some disk errors, yet they always come back if you attempt to fix them.

the c: partition is almost 9 GB's, with (normally) 3.8 GB free space.

I have Win 7 Pro 64-bit installed on a 160GB drive. Today I started getting errors that my drive was full, so I started investigating where all the space is taken up and found that my user directory is 71.5GB, but when I go into the directory select all and see properties it only shows about 100MB.

Where are the 71.4 other GB?

I'm defragging the drive right now, but I have weekly defrags anyway so I'm not sure that will help. Are there some mysterious hidden folders in there I can't see?

There is a real easy way to find out. There is a 3rd party app called treesize pro, by jam software that will show the size of every folder on the HD, even hidden ones. It is free to try

The left is the properties of the drive, the right is all of the C-drive highlighted and went to properties. Where's the extra space going?

Answer:Space Disappearing On Hard Drive

Maybe it's going to a system restore folder or something? Vista has a habit of doing that.
Go to Folder Options and enable 'Show hidden files and folders' - then do the highlight+properties thing.

Incidentally if you're worried about space, install+run CCleaner.

So the other day I had downloaded a bunch of videos. When I woke up the next day after they finished I had a low disk space message. when I checked my hard drive it said that it was full. So I deleted a bunch of stuff off the drive but within minutes it was saying 0GB were available. Ive deleted probably close to 70gb worth of stuff and its still saying I only have about 40GB left. That was this morning. I have yet to go home and see if its gone back down to 0GB available. What would cause this?

Answer:Hard Drive Space Disappearing

The most probable cause is virus or malware.
Run an antivirus scan
Download and run malwarebytes.

If negative
It may be shadow copies, system restore points taking up space

Hello all, I am running a cheapo acer laptop with windows 7. Recently I dealt with a regsvr.exe virus shutting down my works - I got round it by loading a previous version of windows, then installing Microsoft security essentials. Things ran fine for a couple of days, but today I started up the computer, and a few seconds after login/welcome to windows, all the icons except for My Computer and Recycle Bin suddenly vanished from my desktop. The start menu remained, but nothing would open, and I couldn't ctrl+alt+del. Rebooting produces the same result every time, though safemode works just fine. A few seconds after windows loads, my C drive disappears from my computer, signaled by the sound of a usb drive being removed. Doing a virus scan in safemode produces no results. Any suggestions?

Hello, for a few days now my pc has slowly been reducing my hd space. I clean my temp and cache regularly but that doesn't seem to have the effect it used to.

I also wanted to upgrade to SP2, about 2 weeks back, and downloaded the installer but then realized I didn't have enough space to install it. Since then I have an icon telling me suport for SP1 ends october 10th. Maybe it's part of the problem, maybe not. You are the experts. Please help, thanks in advance.

To start with, about 3 weeks ago I installed a new wireless adapter, Asus PCE-N53 Dual-Band Wireless-N600 Adapter. My computer froze up while installing the driver, but after I rebooted everything seemed fine, so I tried to install the drivers again. I don't remember exactly what happened, but I ended up doing a system restore to before I tried installing, and was able to get the adapter working fine.

After that I found that my second HDD, WD2003FZEX 2TV 7200 RPM, would suddenly disappear, along with my dvd drive. Sometimes going to disk management and rescanning would fix it, otherwise I had to do a full reboot. The issue went away when I moved the wireless adapter to a new slot, but came back a few days ago. I tried everything I could think of or find online to fix it, including buying a new hard drive, Samsung SSD 850 Evo 500gb. Problem still persists, except now even the new ssd disappears too, and my computer has started locking up for 3-5 minutes at a time before they disappear.

Things I've tried so far are

Changing out cables and ports
Reseating all of the drives
Taking out wireless adapter
Reformatted both boot drive (adata 64gb ssd) and the WD drive
Updated bios to latest version
Installed sata drivers from the motherboard website, seemed to fix it for a day but then came back again.

At this point I'm just considering buying a new motherboard, but I'd prefer not to fork out the money for that and have to rebuild it myself if I don't have to.

Hi Cllex,

Welcome to Seven Forums! I hope we will be of assistance.

Firstly this could be a number of issues but seen as though you have changed and swapped some of the hardware and the problem still persists; I think we should try look at what has gone wrong in the software.

In the way you have described it, am I right in saying this issue first came about when you failed to install a network card?

When I woke my computer up this morning I had 9G free space, now mysteriously I have only 4.5. I have a split drive with 100G on C and 400 on D which is just a waste as far as I'm concerned. Is there any way to repartition the drives so more space is available on C and less on D? Alternately, can anyone explain where my space is disappearing to even when nothing is being installed? I've cleaned up and moved as much as I can to external drives but even while doing that or compressing, the space disappears and doesn't reappear with reboot.

Hope you can help,

hi all, i know something similar to this has been posted before, but this time its a little different. i've done plenty homework using every solution i could find on the forums but so far i've had no luck.

my windows xp themes keep disappearing and reverting to classic, where i lose visual styles, cursors, and sound settings, but ONLY under the following circumstances.

1. i either hibernate my laptop, or the screensaver runs for more than 5 minutes.
2. and i have a western digital usb hard drive plugged in.
3. after returning from hibernate or screensaver, all my themes and things have disappeared. grr.....

the hard drive is new, and this only started happening since i got it. i've had other external drives before and never come across this little doozy. it looks like windows has stored something on the drive but cant get it back quick enough so it hiccups.

the solution so far is to switch off the drive before hibernate or screensaver. its not a major headache but i'd appreciate it if somebody could shed some light.

Hi all,
I have a Win7Pro x64 box with 2 HDDs - an 80GB boot drive and a 500GB data drive, both Seagate Barracudas. On resume from S3 hybrid sleep, the data drive is often not detected. When this happens, the only way of making it reappear is to reboot the machine - either a "warm" reboot or a shutdown/startup works.

The machine is an HTPC running MediaPortal so schedules itself to wake up to make recordings, and so far (touch wood) when this happens the drive is detected - at least, no recordings have failed yet. It only seems to be manual wakes triggering this behaviour.

Googling the problem brings up many similar problems from ~2009/2010 which seem to be linked to using drives in AHCI mode. However, I'm using IDE mode for mine.
I've tried installing the hotfix (KB977178) anyway, but it just says it's not applicable.
I've tried updating chipset drivers, but the latest version released by Asus only offers to install an "away mode configuration utility" despite other drivers being present in the image.
I've flashed the latest BIOS version.
As far as I can tell, nothing different is logged in any of the Windows Logs in event viewer when the drive does not appear, unless there's somewhere else I should be looking?

Is there anything else I can try, or does anyone know where I can get some chipset drivers that actually install?

Let me know if you want logs or any more info.

Okay, this has been happening for around a week now. Admittedly, my available hard drive space is usually on the low side, but I swear I had over 1 GB free last week, and I've been saving most of my downloads to an external hard drive. The only things that I've been saving on the main hard drive are pictures and text files.

Yet my space keeps disappearing. I have a go-to directory of backed-up videos that I can delete from my hard drive, and I do that whenever my free space reaches 0 GB. I deleted a video that was around 143 MB just a few minutes ago and emptied the Recycle Bin, and my free space is already down to 117 MB.

Considering I haven't downloaded any big files to this hard drive recently, there's a lot of previously freed-up space that's simply unaccounted-for now. I have Windows 8. What could be causing this?

A computer has a 1TB drive as the boot drive (C. It had 800GB of files on it. When the user booted recently, most of the files were deleted from the hard drive. I installed the drive in another computer, and the files show up as deleted. The computer passes malware and virus scans without issue.

I'm currently using Recuva to try to recover the available files (about 80% of the deleted files appear to be recoverable, but some critical files are not.) The recovered files are being saved to an external USB drive.

The only time I've had this problem before was corrected with chkdsk. I'm very cautious about doing anything with this drive until I have recovered all that I can manually.

Does anyone have any thoughts as to what is going on with this drive? It passed Spinrite with no issues. The computer is Windows 7 Home Edition 64-bit.
