Incorrect Hard Drive Usage Being Reported.

Question: Incorrect Hard Drive Usage Being Reported.

Hello all,

I couldn't determine whether this is being caused by the OS or the Hardware, but here goes. I recently decided my HD was due a reformatting. I transferred files my clean (virus-scanned) files onto an external HD and back again after reinstalling Windows XP (SP2).
Reinstalled the most crucial drivers first, and whilst reinstalling various applications, I saw a small notification pop-up in the bottom right informing me that my C drive is running low on storage, then again soon after informing me it's critically low.

Bringing up the properties of my C drive displays the following:

Bringing up the properties of the contents of the C drive (including hidden and protected operating system files/folders) displays the following:
I also opened up disk defragmenter to see if that had anything to say which might help, and though it reports the same inaccurate usage for C, in the top pane, the graphical chart seen at the bottom would indicate that around 50% of C Drive space is unused:
I've never encountered anything like this before and really have no idea how to further analyse the problem; any suggestions apprechiated, thanks.

Preferred Solution: Incorrect Hard Drive Usage Being Reported.

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: Incorrect Hard Drive Usage Being Reported.

What files?

Was it just data files or all of the files on the old supposedly clean drive like Windows, program, and data files?

The rest of the drive is unallocated free space, use a Win98se Floppy boot disc click here after downloading put floppy in drive and double click the file this creates the boot disc. Start comp with disc and let it go to A:\> then type Fdisk follow through and create a Logical Partition of the free space

I have a Windows XP PC (2002 model), and TuneUp Utilities keeps saying that the hard disks are fragmented, even after the TuneUp maintenance shows that it's been fixed.
All the lastest Windows updates are installed.

Answer:Why is my hard drive usually reported as fragmented?

How much free hard disk space do you have? try running Windows Defrag and see what that reports.

A friend of mine had his sdhc card corrupted. His computer frooze when looking at photos on it, he then removed the card and now it can't be accessed anymore. I try to recover the photos on it. When I insert it in my sdhd card reader, I hear the sound windows make when a new periphical is inserted but I don't see the card in Windows Explorer (no letter assigned). I have then tryed Photorec. It search for quite a long time then find the card, but report incorrect size :

524kb Generic-Multi-Card

Instead of 4 Gb it should be. It is noted under this in Photorec :

Note: Disk capacity must be correctly detected for a successful recovery. If a disk listed above has incorrect size, check HD jumper settings, BIOS detection, and install the latest OS patches and disk drivers.

I have tryed several time with the same result. I have also tryed with Testdisk with the same result (524 kb reported). I have not tryed to rescue with this size in fear of losing the content of the card.

The card is a Kodak 4GB SDHC Class 4. I am testing with a know to work card reader on laptop running Windows 7 SP1 32 bits. I have cleaned when contact with a little bit of alcool on q-tips with no change. Also, sometimes the card is not detected at all when I lauch Photorec or Testdisk. I have tryed with both latest 6.13 and beta 6.14-WIP Photorec. I have also tryed the card in another digital camera with an unusable error message. Any help will be greatly appreciated.


Answer:Photorec incorrect size reported

The card (or rather it's contents) may already be too corrupted to recover anything.

Answer:Photorec incorrect size reported

I have been answered in another forum. The answers were :

You have gone about as far as you can go on this one without special tools and knowledge of file structure. You need to do a recovery of this card but programs will not do this one for you. You need a special reader and understanding of how to reconstruct the file structure to do this one. You should try a DR company who specializes in this type of recovery and has the tools to do this with. Good luck


Ann is correct, you cannot proceed further on your own with this one.
Suggest you contact Eric at Datacent in Canada or Luke at Recovery Force, they will be able to sort this out for you.

Every alternate boot, the reported free space on one of my two drives (Total 40 GB) reduces & increases by about 400 MB. I've turned System restore off, run 'Wipe Free Sp[ace" with BC Wipe & still this variation persists. What could it be?

being slightly 'anal', i am compulsively booting twicew before using the comp so that i start with a correctly reposted 'free-space'. Its driving me nuts!!

I have Zone Alarm Security Suite & WinPatrol installed. Also run Ad-Aware SE Personal & Spybot S & D regularly - so i have good protection. Someone please share your experience & suggest a solution.

I recently purchased a refurbished E-machine, and after having to replace the memory, finally got it to load windows, and reboot corrrectly. I did wipe the hard drive, and reformat by writing zeroes, then used the restore disks, and re-inatalled the o/s, as it had gotten corrupted after the memory crashed. I now have it running properly, but the HD does not show correctly in the device manager, or in the properties for each drive under 'my computer'.

The HD is a Seagate Barracuda 80GB (7200rpm). I have downloaded (and ran) Seagates 'Seatools' Desktop utility for checing the HD. It found numerous errors on the first test, and I selected to let it correc them, then ran it again, and it found 2 errors, and I again let it correct them. Both tests showed no problems with the memory.

The properties within my computer for each are as follows:
C: (Local Disk) 28.0GB Capacity / 19.1GB Free
D: (Recovery) 3.47GB Capacity / 1.66GB Free

Is there a way to get windows to recover this free space that is not being reported?

Hello all. I am a new member of this forum and I am trying to get some questions answered on my  ThinkCentre S50 system. Since 2007 I have a ThinkCentre S50 8183-TSG that I use for Photoshop, now version CS5. In order to enable Open GL for advanced graphic options and improve general performance I placed 2 GB of RAM and a GE 8400 GS PCI type graphics card. This works just fine. The system came with two partitions on the hard drive, C and D. Considering the capacity of the drive I wanted to make just one partition of this. I used a program to erase the D partition and take the free space into the C drive but now the 160 gb hard drive is only reported as 128 gb. A search on the Internet indicates that this can be a BIOS limitation, the BIOS version is 2AJT51A which I believe is the latest. I am running Windows XP Home edition, updated to SP3 with all the latest updates for everything. Can this be solved or do I just have to live with it. I am not in the mood to format the whole thing and reinstall everything again. Kind regards, Hans

Answer:ThinkCentre S50 8183-TSG 160 gb hard drive reported as 128 gb

Hi and welcome to the forum!

Based on this, your HDD has 149GB actual capacity.
If you go to Disk Management (Right Click on My Computer -> Manage -> Disk Manangement), does the space add up to ~149GB? Do you see any uninitialized drive there?

Looking for help on a strange problem. My drive C reports 220gb used with right click properties yet when doing a rough count, or more scientifically using Tree Size it reports about 25gb. Only other operation that I am suspicious of was that I was using Norton Ghost to back up until I realised that doing that to the same drive was not clever as it was backing up the backups. I stopped that and deleted the 'large' ghost files. I have defregged, analysed with 'fix-it' and Norton but no change

I have an issue which I think is related to this with my computer. On my second harddrive ( the one that I am not booting from) I have 31 gig "missing". It is suppose to be a 100 gig drive. I dont think this is a virus, since the amount does not seem to be changing and I have been adding and deleting files from this drive. Free space does change as you would expect, with the addition of this 31 gig that is being "used."

OS = Windows 2000 Professional

Reported by Explorer:
Capacity = 93.1 GB
Used = 79.8 GB
Free = 13.3 GB

Reported by properties window:
Size = 48.1 GB (51,681,556,778 bytes)
Size on disk = 48.1 GB (51,661,704,491 bytes)

I know about hidden files and have windows set to show them, plus this drive should not have any because it does not have an OS installed on it.

I've got a friend who is experiencing that problem. I used to have the same probelm too, but it just got solved after a few reboots. I told him to defrag his partition, but that didn't work. I told him to disable "System Restore", because I know it takes up space, but it was already disabled. He scanned for adware and spyware with Ad-aware, Spybot - S&D, and Ewido I think, all updated. I saw he had this "Indexing Service" enabled on that particular partition, so I told him to disable that too, but it just changed the free space a bit, though not to the correct value. I know he has two partitions, the troublesome one is C:, it's NTFS, and the capacity is 7.81GB, the other partition's (D capacity is 29.4GB, and it's FAT.

So, why does it happen? Is there any way, other than format, to fix this problem?

I am running Win98SE with a 40GB Hard Drive. I am constantly keeping an eye on my free space, and watch what I download, but recently it has been running very low on space. Even though I have been downloading things, collectively, they could not equal the amount that is taken up each time. On My Computer it says I have 700mb or so left, but when I select all the files/folders on the root of my C drive it only comes upto about 33 Gig. I dont know if that method is entirley accurate and I know somethings arent accesible through the windows explorer, but could someone give many any advice or tips to be sure of my Free Drive space?Any help appreciatedConor,

Answer:Possible Incorrect Free Drivespace reported (Win98

hidden and system files including the swap file which changes size depending on what you are doing can account for some of the "lost" space, formatting and the manufacturers way of describing drive space can also take a few gig's of space from the "40" gig advertised.a 40 gig drive after partitioning and formatting would probably pan out about 37gigi think really its time to invest in another drive if you are so close to filling the one you have. as hard drive prices are so low at the moment, now is a good here are offering free delivery in december. worth taking a look. also check click here

My Windows XP Pro SP2 laptop reports to me that I have 2.66 GB free on my C drive, which is a 40 GB drive (37.2 Gigs formatted). Yet when I add up the size values for every folder on the drive through My Documents-> Properties (with it showing all Hidden Files and Folders) it adds up to 25.15 GB which would theoretically leave 12 GB open. But, again, it reports only 2.66 GB free.

I just attempted to add files that totaled 3.36 GB to it from my external drive to see if it let me. It did not, but when I checked the free space after deleting the test files, it said 5.02 GB.

Does anyone know what's going on and/or any way to fix it?

Hi my advent monza t100laptop was turned off by my grandson shuting down and when I turned it back on I get aptio setup utility on screen and been told lost harddrive can I use my advent vsta harddrive and ry that in monza t100thanks

Answer:Hard Drive reported as empty after accidental power off during shutdown

What is the exact error message?
If your are getting the Setup Utility, then you probably still have the HDD and it is not lost. The HDD may, however have failed.
You can create an Ubuntu Live CD and boot off of that and it will allow you to browse your C: drive. This will also confirm that you do have a C: drive still and it is not lost. Then you can save any personal files to a USB HDD.
Once you are safely backed up, you can Run the Setup Utility and restore the computer to Factory Defaults. If that fails the HDD may need to be replaced and Windows will need to be reinstalled.

Hello Gang,

One of my drives was running low on space, so I moved files from another partition to the right, to a different drive and deleted the partition. I then resized the drive low on space to fill the new 20GB that I had just cleared. This was fine and no errrors were reported. However, after a restart a while later I noticed that both disk management and explorer reported I had 5GB free on the drive, even though it should have been roughly 21GB.

If I open explorer and select all folders on that drive and look at the properties, it shows 29.6GB of data. The drive has a capacity of 60GB, and shows only 5.71GB free. This makes no sense at all.

Please see the image attached.

Is there some kind of counter in the registry that maintains these numbers?


Answer:Incorrect Free Disk Space Reported After Partition Resize

Please post a snip of your maximised disk management

Some files, for example windows image backups, will not display there size as they are hidden but i suspect your issue may be that space is being used by system restore, recycle bin, pagefile & hiberfile if you use hibernation
There are some settings you can change to alter this depending on your setup

I have 8GB of RAM (7.90 usable) and I get "Your computer is running low on RAM" messages, up to the point where Windows asks me to close programs or even closes some. The problem is I don't see this reflected in the Task Manager -> Memory column for the running processes. Any idea what's eating up my RAM or why Windows is falsely reporting it's low on RAM?

Screenshot: the reported RAM adds to around 2GB, but the reported 77% would mean 6GB are being used. What's up?!

Answer:Abnormal RAM usage / reported usage

Post a screenshot of Task Manager - Performance tab when the problem occurs.

Adding up the items in the process memory usage column will never equal total usage. It was never intended that they would. There are major users of memory that are not processes, not all of which are shown in Task Manager. And in this case not all processes are shown. You must select "Show processes from all users" to see all processes.

The error message states that the computer was low on memory. The problem usually has nothing to do with RAM at all.

I recently ran into a situation where a rogue anti-virus application was still being reported by Windows Security Center as being installed even though it had been removed. Someone else here experienced a similar issue.

After doing much web searching, I managed to stumble across this page:

it provides steps on resetting the Windows Security Center catalog it uses to "know" which anti-virus apps are installed or not. This info is also useful if you've uninstalled one legit anti-virus app and are trying to install another legit one. In the event a legit anti-virus app doesn't do a "clean" uninstall, the steps on that page can help Windows Security Center recognize the old app is no longer installed.

I have done this on the Windows XP system I mentioned above and it worked well. I started this thread to make others aware of this in the event they are fighting with Windows Security Center erroneously reporting multiple anti-virus apps being installed.

I have NOT tested this procedure on multiple systems or different releases of Windows so if you decide to give this a try, USE CAUTION!


Answer:Info on correcting incorrect anti-virus software reported by Windows Security Center

I wanted to add that you can take care of this manually in XP:
1. Click on the Start menu.
2. Select Run...
3. Type wbemtest and click OK
4. Connect to root\SecurityCenter
5. Click on Query
6. Type in or copy/paste SELECT * FROM AntiVirusProduct and click on Apply

If there is more than one result, it means there is more than one Antivirus program installed. Double click on each result to view the properties for that Antivirus product. Identify the product(s) installed and DELETE any records for an Antivirus software that is no longer installed.
For the firewall listing you would have to query SELECT * FROM FirewallProduct

I was wondering why windows does not accurately display the amount of storage space on hard drives.

For instance, I have two computers both with Window XP and both with 40 gb of storage. One computer shows 37gb total and the other shows 38gb. As well I installed a 160gb external hard drive and it only shows 149 gb of storage space. Thats a whopping 11 gb of lost storage space.

I have never seen the storage space on a hard drive accurately displayed. Why is that?

Thanks for any comments.

Answer:Incorrect Hard Drive Readings (Gb)

The amount displayed is correct. In computer-ese. a kilobyte is 1024 bytes. But computer manufacturers are still using the kilobyte as 1000 bytes. The result is that their drives look bigger to potential customers than they actually are.

Occasionally, when an OS is being installed, its setup uses a small partition for the setup process. In XP, that partition is 8 megs. That partition is not returned to the larger partition when the process is over, but it's only 8 megs and not worth worrying about.

If you get about 74 gigs on a drive that the manufacturer says is an "80 gig" drive, that is the real amount that you have.

Hi everyone, I have an external hard drive with about two years worth of data saved on it, something like 700 gigs, and it's always worked fine for me, until yesterday. Two days ago, I dropped it, I picked it up, plugged it back in, and it worked fine. I come back the next day and I notice that Windows 7 is struggling to recognize it, and when I open it in My Computer, it just says "Parameter on G Drive is incorrect, data not accessible," something of that nature.

I don't really know what to do, I haven't reformatted it because I don't want to lose the data but I don't know what else I can do, which brings me to my question: What can I do?

Answer:Parameter is Incorrect on my external hard drive

Dropping is not a good thing, ever....Have you tried hooking it up to a different computer? Just in case it's a driver issue...

I have recently got a new computer and installed Vista x64 home basic onto it. All was seemingly going well untill i looked in My Computer and saw that when i clicked on properties of the c drive it showed i was using 68GB of space. This was just days after i had the computer and i thought that couldnt be right....I only had Crysis and Battlefield 2142 installed aswell as a few other little programmes. I tallied up the size of all the folders in the C drive and it only came to just over 30GB. So why on earth has 68GB of space been used on my hard drive? Is this just the information being relayed incorectly by Vista, meaning i havnt actually used all that space? Or are things being installed twice on my system in a folder i cannot see? The space being used seems to fluctuate dramatically too. For example i can check and it'll show 68.8 GB being used, then i will check 10 minutes later and its at 70.2 GB without me having installed anything new.

Any help would be apreciated guys. Is there any other way to check the actual space being used on my hard drive? Is this a known problem? Thanks for your time guys.

My inspiron 620 was indicating an issue with the hard drive which indeed crashed later
I purchased a new hard drive, however I could not insrall Windows on it.
After several tries I run the diagnostic tool which is indicating the error code 2000-0151 incorrect status E3
As I doubt that the new hard drive is damaged too, would you please tell me what could be the issue  (mother board...)?

Answer:Desktop new Hard drive incorrect status E3

Did you format the new hard drive?
Did you connect the new drive to the SATA0 port on the motherboard?  Have you checked the connections to the new drive?  You can also reset BIOS to see if that clears the error. Unplug PC and press/hold power button for ~15 sec. Remove the motherboard battery and press/hold power button for ~30 sec. Reinstall the battery.
Now reboot and immediately press F2 to open BIOS setup. See if the new drive is correctly recognized on SATA0.
And it is possible the new drive is defective...

Hi all,

I have what I think is a unique situation. i just upgraded to a newer box with an existing primary drive. On my old machine I had XP and Windows 2K. When I used W2K my two drives were known as C and F. When I upgraded to XP ( and stopped using W2K) on the old machine they became known as C and D. I transferred my two drives (C and D) to the new machine and in the process the new machine now sees the drive that was my D as the old F drive. I know this because the files that are available are files that were on the F that I haven't accessed since I upgraded to XP. The result is that all of the files that I created in the last 3 or so years are unavailable to me because the new machine thinks the drive is old F drive (Pre-XP). I did a search and was shown shortcuts to the files but not the files. The search also showed the files were on the D drive. Clicking on the shortcuts was a dead end (invalid path). I know this is a pretty crazy thing. My regular computer guy has never seen anything like this. I hope someone can help.
Much thanks.
PS. I have back-ups to a lot of the files but not all of them.

Hello everyone, i know the title sounds amateur-ish, but hear me out. I have my windows installation on a different hard drive than the one i'm talking about.

a friend of mine had a computer with a RAID setup for the hard drives in it, but after one failed, he just replaced them both and i took the one that was still good and formatted it. I have since been using it as a backup hard drive for specific files.

It is a 500gb hard drive, but it only shows 338 free after a format, if i go into properties for it it says there are 146 MB used, but you can't even see a sliver on the pie chart. I was thinking that being put in a raid setup had changed the partition somewhat and had redered part of the drive useless. Should i do the Diskpart utility from cmd prompt? last time i used it on a flash drive that memtest had rendered useless i still couldn't format the flash drive and has since been useless to me, even though i followed all of the instructions that many others had said worked for theirs. I just don't wan to ruin this hard drive by trying to squeeze a (possible) 100 extra gigs out of it.

If anyone has any suggestions, i would greatly appreciate you sharing your knowledge with me.

Thanks a lot.

I need help on an external hard drive problem I'm having now. I have a Western Digital 160gb IDE hard drive in an external USB enclosure. I set it to CS on the jumpers, and it detected the drive, and I was able to access all files with some permission issues. Then a power outage occurred and when I connect to the drive, it runs but I can only access certain files and folders. Other folders take along while to access then I get this message: folder not accessible: Incorrect Function (see image attached).

I've tried connecting the drive to another computer and it opens the folder but it's blank?! The drive itself indicates that there's about 127gb stored. The folder i'm trying to access has about 117gb of data. Also when I try to safely remove hardware for this drive, it stalls for a long time.

I've also tried another smaller 60gb WD hard drive and it works fine when I connect to the enclosure although it's a blank drive with no data. When trying to safely remove, it works fine.

It's strange that the drive was able to be accessed prior to the power outage and now it's not and seems really slow.

I'm running Vista Home.
Please help.

Hi, I recently purchased a Dell Xps 1340 laptop that came with windows 7 32 bit professional. After a few months, I needed to wipe the hard disk, and so I did. Before I did, I extracted my product key with a program that I downloaded off the internet. I got the following information:

Windows 7 Professional

Installed from 'OEM' media.
Product ID: ******* match to CD Key data

Anyway, I had a RETAIL windows 7 professional disc, and I installed this onto my dell laptop. However, it keeps telling me that my product key is wrong when I try to activate. I have tried both 32bit and 64bit

Hi, I have a SSD and a HDD. What happened today is that I changed the SATA ports my SSD and HDD were plugged into.

P67A-GD65 SATA Performance |

Basically I plugged my drives into the Marvel controller on my mobo by mistake as my manual did not say which port was which. I only realised the performance difference after reading the above article (the Intel P67 ports are faster on my mobo). So i open up my pc and switch the ports they are plugged into. (i changed from sata7_8 to sata 1_2, both 6gbps)

HD Tune Pro does register some performance increase from changing the SATA ports. However, the WEI index now says my Hard Disk score is 5.9. It was before on 7.7.

I suspect it's reading the HDD as my primary hard disk? because there's no way my SSD is broken. it doesn't feel funny and HD Tune Pro sees no errors and some performance increase.

Answer:Windows Experience Index - Hard Drive score totally incorrect

Honestly, if the system is running fine, it isnt worth the effort it took to type in your entire post. WEI is not a benchmarking tool and shouldn't be treated as such. It is utterly and completely useless. I haven't cared about the my score the entire time Windows 7 has been out, but in Vista, I could occasionally get a different score just by refreshing the tool a few times. I'd completely ignore it.

HD Tune Pro is a better indication, and it is showing a difference, going by your post, so that's all you should worry about. I have a Gigabyte board nearly identical to yours, and considering the chipset bug, you should be using the first two ports...which you are now. They are unaffected.

Answer:Hepl me with T430 with Hard drive test by LSC reported Targeted read test Failed

Hi, quocphong
It sounds like the hard drive is running okay overall, but it has some bad sectors in it. You will not be able to read or write to these sectors. That being said, I would first try running a ChkDsk on the hard drive and see if any of the sectors can be repaired. To run a ChkDsk, go to Computer and right-click on the C: drive and select Properties. Navigate to the Tools tab and select the box that says Check now... This should scan the drive for errors and attempt to fix them if possible. The test can take a while, so I would do it when you will not need access to your computer.
If the test is not able to fix the errors, then I would contact Lenovo at 120-11072 (Toll Free) or +(84) 8 3521 8000 (Standard Charges Apply) and discuss a hard drive replacement with them. As for Windows, you will need to ask for recovery discs as well. Lastly, I would backup everything on the current hard drive so that it is not lost.
Hope it helps,

The PC is amazing, it performed beautifully in everything I threw at it, the only weak point was Windows 10.. I started to get random OS hangs without cause when playing games or doing general browsing, I thought I had an issue with my GPU or something but it turns out after some investigating that it was a Windows problem as when the hangs would happen I quickly would open task manager and see that my drive usage was at 50% having two drives this meant one of them was under 100% usage and so I wanted to find out what was doing it, I looked into performance monitor and other programs to try monitor usage but nothing other than the typical system process was using it.

I did the normal fixes, disable Superfech and Windows Search etc. Neither helped, I clean installed 3 times, no luck.

My laptop (Lenovo Y510p) is always at 100% disk usage for the first 15-20 minutes of starting up, and for intermittent periods afterwards. During this period, everything essentially freezes including the Start Menu, Task Manager, and all other apps running. After about 5 minutes, the hard drive "catches up" and everything starts working again.

The strange part is that when looking at Task Manager / Resource Monitor, the total read/write of the hard drive does not appear to be very high - ie it will be at 100% disk usage but the highest program is reading/writing maybe 0.1MB/s.

This is causing the laptop to become borderline unusable. I have to leave the laptop running in order for it to be usable, as shutting it down / putting it to sleep will cause the hard drive to go back to 100%, and everything comes to a standstill. Please help!

Just wondering, but does the Task manager not show the correct CPU amount that is being used? I am showing 90% - 100% usage currently on task manager, while Intel XTU is showing 65%-75%, and CoreTemp showing similar numbers to Intel XTU.
Which numbers would be better to trust? 
I use an i7-3770k overclocked to 4.2Ghz with Windows 8 Pro.

Answer:Incorrect CPU usage?

It has been awhile since I delved into this but I believe that in Windows the idle task is used in the calculation. You see it listed as System Idle Process. Then the remaining CPU usage is divided amongst the other tasks based on how much work each task has queued up. The calculation is done by the OS.
It is certainly possible that the Intel program determines CPU utilization in a different way and that would explain the difference. I think Linux does it differently also (no idle process).
You could try a Linux LiveCD and see if it reports similar numbers to the Intel program (if the Intel program has a Linux version).
So both numbers are correct. They are probably just using different algorithms. Since you are running Windows, you should go by the numbers that Windows gives since Windows will make decisions on allocation of resources based on its own calculations.

Answer:Phantom usage of my hard drive.

Make sure that your windows explorer is set to display hidden and system files and look again. If this does not help then drop down to DOS and type "DIR D:/S" without the quotation marks and see if anything shows up.As a last resort (and you are very sure that there are no files your computer needs on drive D) you could always format it and see if that solves your problem.

Hey guys!
Please don't bash me for posting this (as I can see others have posted about it also). I just want to make sure I can get as many ideas as possible, before I do a clean install/new hdd.
I am helping a family friend fix their desktop. It is only about 3 years old and has a AMD quad core processor, 8GB Ram, 1TB HDD(500GB used) - They also have a smaller 2nd HDD - Though I am not sure what the contents are for. They told me the computer has been running very slow since October.
So I did my usual computer cleanup steps:
1. Malware removal (Spybot, Malwarebytes, SuperAntiSpyware, Hitman Pro, Emisoft Emergency kit) - All in safe mode - nothing serious found.
2. Ran CCleaner (Cleaner,Registry,Startup) / Deleted temp files
3. Checked for unwanted programs - found none
4. Google Chrome is their browser - no plugins/extensions to remove
5. They have AVG Internet Security, scans only at 9pm everyday
At this point, I still felt the computer to be very sluggish - After looking at task manager, I noticed that the disk was always at, or close to, %100 usage. **No 1 process was hogging it all**
**Decided to let Defraggler to Defrag the PC - And that is where I am at now** (Gives me time to research/jot down things to try - will be doing further work remotely on the PC(Teamviewer))

According to Windows 7, my SSD that is 128GB has 100GB used. WinDirStat says that only 52.8GB are being used. How can I figure out what is using the additional space??

Attached are screen shots of what Windows says and what WinDirStat says.

Interesting, never saw an EFI partition like in your pic.

Maybe that accounts for the discrepancy?

I have a system with a P4 processor, 1 gig of RAM, XP Pro SP 3 that seems to run OK except the hard drive is constantly hammering away. I have good AV and SpyWare programs installed. I will be doing nothing on the computer and the HD is busy doing something.
Is there anyway I can tell what the HD is doing or why it is in use so much????
Any ideas would be greatly appreciated.

I am request info on a better way to back up external hard drives. we would like an automatic back up that would back up new files on a daily basis.

Currently are running Windows 7 home edition,500 gb on a 64 bit laptop. we have approximately 3.5 t< A 1.5t,a 1t,a 500gb,a 320gb, and a 250gb external drives in addition to the 500gb drive on the laptop> of external storage< hard drives, no server as of yet>. We currently save mainly Pictures and art for digital scrappingbooking.

It seems that no matter how many external HD we get they fill up rather quickly.< 3 to 6 months>.

Is there a way to set up software to automatically update new files daily?
I am considering a 2 t external for a back up to the current drives we have.
All of the family pics have been saved to these drives, so a loss we not be good.
We tried mosy but the uploads seem to always get stopped by our Internet provider, because of size.

I appreciate in advance any advice that can be offered

I am looking for a way to get real time data on what is accessing my hard drive. I know about the indexing problems out there with windows but it hate that the only real way to tell if your hard drive is being accessed is to look at the light on the front of case (I think).

Anyone of a monitoring tool for this purpose?


Answer:Hard Drive usage utility?


Could try Process Monitor monitors read write access on a HD and what location. Use Show File System Activity from top menu and un-highlight the other options, its the four icons top menu towards the right.

This is a new one for me, migrating data from an XP system to a new Windows 7 Home Premium system.  On small drive previous system I always dump the entire contents into a folder for customers in case down the road they remember some strange location where they had some data stored.
Windows 7 shows 11.9 GB free of 38.2 GB (approx 26 GB used) connected with an IDE to USB cable, but when I dragged the entire drive to a folder it was only showing about 4 GB worth of files.  Discovered the user had made files private trying to implement a "secure XP system". I took ownership at the drive level for all subfolders and objects and still am only seeing 16 GB of files . . . somewhere are 10 GB of missing data.
The XP system is not bootable so I can't do a comparison on the actual running system either.
User is a bare bones knowledge user and I don't see any evidence of a TrueCrypt installation. 
Comments? Questions? Any thoughts appreciated.

Answer:Hard drive usage discrepancy

Another oddity, if I CTRL A and right click at the root of the XP drive I see 50,148 files and 5,320 folders, but if I drag everything that is selected to a folder on the Windows 7 drive the dialog box reads copying 3,889 items (1.64 GB) . . .

I have a Toshiba Tecra TE2100 1.8 GHZ P4 laptop with 768 MB RAM. I purchased an external enclosure for a Maxtor 60 Gig IDE hard drive. After starting Windows XP everything is running normal. As soon as I turn on the hard drive my CPU usage skyrockets to 100% and everything runs incredibly slow if at all and the computer won't shut down. When I turn off the drive things return to normal after about 15 minutes. Sometimes Windows comes up and says the drive is installed and everything runs except for the fact that there is no drive letter, but I believe I found a workaround for this in these forums. If I could just solve this CPU problem I believe everything will be ok. Could these problems be related? I have spent hours trying to figure this one out.
Thanks For Your Help,

Answer:USB Hard Drive = CPU 100% usage - Explorer

You should try to fond out what is using 100% CPU. It could be your antivirus program or Windows itself or the USB storage drivers. Could be a damaged filesystem on the drive too. Or maybe the drive is bad..

I have a Dell AMD 3800 2gh 2g RAM 240g HD and something is filling my hard drive to capacity and I cannot find out what. I recently installed Carbonite and it appears to be running fine. We noticed that some recorded TV shows suddenly disappeared and when looking found the hard drive within 3g of being full. I started backing up and deleting video and picture files and I will notice that space being freed up on HD but then it fills back up again without us saving anything. This morning after deleting files I had 9.4g free but right now it only shows 5.97 free. I did empty recycle bin. I tried to run CHKDSK but could not as it said I needed higher security. I am the Admin on Vista Home Premium so should be able. Can someone help me through the steps to check what is happening. Thank you in advance.

Hi All,

I have a customer with W10 that is next to unusable.

Is there something out there in the Windows 10 world right now that would cause 100% hard drive usage, slowing a computer down to a crawl?

I found three anti viruses duking it out and fix that.  But CPU goes to 100% (system) and drags the computer to a crawl. Pulling the power plug resets it for a while.

I have not found any root kits or the like.

I am wondering if this is one of M$'s endless full rebuild updates?

Any words of wisdom?

Hi all,

My vista box is getting a little slow from time. Like everything freezes on the computer, and then I have to wait a little bit and it comes back. Often this happens when firefox has been used for a while. I'm not sure if this is firefox's entire fault, so I was wondering what free program is out there that I can use to monitor what application is accessing the disk. I tried googling but just found a bunch of hard drive monitoring (temperature, fail rate, etc.) programs.



Answer:application hard drive usage program

You should be able to use the resource monitor built into Windows to see what programs are writing to disk.

Third party utilities are available as well, such as ProcessMonitor and FileMonitor.

Here's what I am working on.

Dell: P-233 Latitude Laptop

Here's what I have done:

I got this computer used. I formatted the hard drive first, then I went into FDISK.
I noticed that when I hit Diplay info it shows this:

Partition: C:
Status: A
Type: Pri DOS
Mbytes: 2047
Usage: 66%

What Im concerned about is why does it show 66% usage? Does this mean it is only using 66% of the Hard drive? And if so how do I set it to get 100%?
When I set the percentage to l00 I notice it will still say only 66%...


Also: What WIN operating system in your opinion would work best with this computer being only a P233? I see it says it was built for WIN95/NT....

thanks again

Answer:Dell P-233 Laptop - Hard Drive Usage says only 66% - Need Help!

Sounds like you used an old version of FDISK or you did not enable large disk support when it asked in FDISK. Windows 95 at first only support a 2 Gig partition. Later versions support bigger partitions. What Windows are you using? If 95 you will have to just create an extended partition and format it. If Windows 98 you must use the windows 98 Fdisk to delete and create a new partition and don't forget to enable large disk support.

Hello all :)
Our son recently bought me a new computer, a Dell XPS 8920.  Though I've read about and watched some YouTube vieos, and not being a computer guru, I'm having a difficult time understanding how to set up the OS (C) & D Drive.  I realize you cannot download a ton of programs onto the OS (C) and have to revert to the D Drive.  Especially if one uses a lot of photoshop programs like I do.  I believe I understand you can set up a Folder on the C Drive that will direct to a specific program on the D Drive but, I'll be darned if I can figure out the process?
Anyway, is there a book, something online, I can download so as to understand how this Drive system differs from the standard C Drive when it comes to downloading multiple programs?  What I have found is short on details and seems to presume one knows a lot about computers...which I do not.  I wish the new PC had come with a users manual of some kind.  So, any help will be greatly appreciated so I can finally start using this XPS properly.

Answer:Cpu usage 100% with external firewire hard drive

Hi, I've got a problem with an external firewire hard drive (a Lacie d2 drive). When I try to access the drive in explorer (just browsing through the files and directories) the cpu usage rockets to 100%. Shortly after that explorer freezes, and cpu usage goes back to normal when explorer is shut down. Needless to say that the external drive is pretty much useless for the time being. I reinstalled the OS and the necessary drivers but the problem persists.The computer is a recent one with Win XP as OS. The motherboard only has USB 1.1 support so I bought a firewire-USB2.0 combo card. I just can't get the Lacie drive to work on that computer. The same external hard drive does work normally on another computer (also Win XP as OS, but with a firewire expansion card).If anyone could identify what the problem is, it would be greatly appreciated.Thanks in advance.

I was wondering where all my hard drive space has gone today, and I wondered if a program that could show you what was on the hard drive existed. Kind of like a pie chart of your hard drive - each segment belonging to different categories.

How do you know if you have monitor damage? I replaced a G-Force 32mg graphics card with an ATI 256mg Pro card and the instructions said to certify that the optimal monitor refresh rate and resolution are the same as the graphics card configuration otherwise damage can occur with the monitor. The monitor is set up for 1680/1050 60hz. I ran it on 60hz but then something like 960/720 for a while. I never did gaming on it. Now there is a noticeable blemish on the monitor screen when viewing the desktop that wasn't there initially. What do you think? The monitor is still under a two year warranty.

Answer:monitor damage from incorrect usage

If its under warranty and its the monitor that has the defective and not the video card then by all means return it. I'd say its pretty hard to damage an LCD by using a lower resolution, but he image quality will definitely be less then optimal.

So I have a Windows 7 64bit desktop with 2 external hard drives that have shared over my network so I can view the files on my laptop(win 7 64bit) and watch movies and such on my xbox via windows media center.

I recently purchased a WD Elements 2TB external Hard Drive.
I connect the new drive to my desktop along with the other 2 external hard drives and functions with no problems until I try to share it on my network.

My procedure for sharing was opening my computer, right clicking on the hard drive, clicking share with.., advanced sharing, (in the sharing tab) advanced sharing again, click the share this folder box and hitting apply. And I get this error, "An error occurred while trying to share G. Incorrect function. The shared resource was not created at this time."

I was however able to add the new external hard drive to my media library in windows media center so my xbox can see the new hard drive no problem.
So now I need to get the drive on the network so I can see it on my laptop.

Whats more, If I disconnect the hard drive from my desktop, and connect it to my laptop, it will let me share it and I can see it from my desktop. (Baffles me...)

Any help or ideas on this would be greatly appreciated.

Answer:Cant share external Hard drive "Incorrect Function"

I see you have the same issue as I do and are getting about the same help I have been getting, NONE
We will probably find out "Microsoft" will want to charge us extra if we want to share more than one way, they give us ONE free sharing but not 2 without more money.

I mapped a few network drives to different shared folders on my EX485 with the inital 750GB drive installed. Since then, I have installed an additional 2x1TB. However, in Windows 7 it is showing 1.18TB free of 678GB, so it recognizes the correct free space, but is still showing the old HDD total. I've removed the mappings and readded and rebooted both my PC and WHS with no luck. Any suggestions? Thank You!

My network drive mappings never show the correct free space either. I just ignore it.

I have extensively searched these forums for a solution to my problem but can't find it. I have found some similar problems, but none exactly the same, here is what happened:

I have a Windows7 computer running just fine. I pulled the hard drive out of my old computer and had installed it in the new one and it seems fine. I can access both drives and i all my files are there. The problem i am having is that i can't open any files from my old hard drive if the program they need to open is also on that old hard drive.

For example, my old hard drive has AutoCAD on it, my new hard drive doesn't. When i click on AutoCad i get the annoying "The application has failed to start because its side-by-side configuration is incorrect" message. This happens with lots of programs, not just AutoCAD. I have MS Office on the old hard drive but when I try to open a word or excel file it won't open. It's like the computer is trying to open files from my old hard drive with applications that are on my new drive. This is a problem because i cant afford to buy 2 copies of autoCAD and 2 copies of MS Office and 2 copies of every program i have.

I feel like there is a simple fix for this but i can't figure this one out.
Thank you for help!!!!

Answer:Installed 2nd hard drive....side-by-side configuration incorrect

Hi welcome to the forum.

to my knowledge you will need to reinstall the programs as you cant use programs that are installed on the hard drive from another computer as it will have writen registry items when the program was installed.

My laptop is running slow and the battery drains too fast, and the hard drive just starts going constantly sometimes; it's half-full (out of 320GB), I've already cleaned up, defragmented, run virus scans with various anti-virus products, and something is just dragging it down. I can't tell if the hard drive is dying or a bunch of programs are sucking up resources (like anti-virus).

I only know how to use Task Manager, and I'm not seeing how to track usage over a day or so.

Is there something I can use? What would be the best and what are some other good ones?

(Note: I've used Process Explorer but I'm not getting much more valuable information out of it)
