Can't get past "Unknown Disk" problem installing XP Pro - floppy drive issue??

Question: Can't get past "Unknown Disk" problem installing XP Pro - floppy drive issue??

Hi -
I'm trying to install XP Pro onto a brand new SATA hard drive since my old one seems to have gone kaput after about 5 years.

I booted from CD, and went thru all the screens to the point where it was ready to start the installation. When i got to the screen to partition the "mass storage device", i got the following:

Unknown Disk
(There is no disk in this drive.)
Unknown Disk
(There is no disk in this drive.)

So i found an old post on this site ( and followed the lessons learned there, and realized I had a floppy for a RAID DRIVER i had forgotten about (it came with the components I bought to build this box). So i tried the installation again, starting from a reboot, and hitting F6 at the right time. When it came time to install the 3rd party driver, i inserted the floppy as instructed, and hit Enter. The floppy light came on, but i don't believe i heard it do anything, and the screen asking me to insert the floppy quietly came back.

I tried a couple times, but still the floppy did not do its magic. I continued, and the partition screen still showed the Unknown Disk error. So as suspected, the driver did not get installed. I then rebooted, this time hitting F1 to check out the BIOS. My BIOS recognizes both my new hard drive and the floppy drive just fine, and the floppy itself can be read just fine on another PC.

Could this be a floppy controller problem? is there a simple way to test it? I'm not sure of the last time, if ever, i've used the floppy on this box. Does the BIOS recognition prove that it should be functional?

I've installed new OSes onto new HDs a few times without problem in the past, but am no expert. So I may be missing something simple. Any help would be greatly appreciated to figure out my problem. Thank you.

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.

Hello, TSG!

Just yesterday I was using the computer normally until I got a Blue Screen. Getting a blue screen is usually something normal that occurs to my every so often, so I didn't mind it and rebooted the computer normally. However, I got two more blue screens within the next hour. The 3rd time rebooting, my computer starts to act strange as if it had a virus. Upon powering up the monitor would just display a black screen with two lines about something --- which I don't remember, sorry --- and stayed like that unless I plugged out the power cord or held on the power button to shut down. Then when after a few tries it boots and displays a message "Floppy Disk Failure" and "Drive 1 not found: Serial ATA, SATA-1" (and the same message for Drives 2 and 3) show up. Also it asks me to continue loading by pressing the F1 Key.

When Windows loads the first time, it displays a message saying a bunch of hardware has just been installed and ready for use. Also, my internal clock resetted itself back to Monday, November 07, 2005 (Which, if I recall, is the date when I got the computer) and my speakers do not work.

TL;DR Version
3 blue screens within a short time
Floppy disk fail
Drivers 1-3 not found: Serial ATA, SATA-1-3

Anyway, I browsed through Google but I haven't seen anyone with both problems. I disabled my Floppy Disk Drive and that message doesn't show up anymore, but the others do and my computer still isn't fixed. I ran a vir... Read more

I have added a SATA drive to my Vista machine that was once loaded with Win XP, the Device Manager does pick it up as well as Disk Management, but under Disk Management it states the drive is "Unknown" and "unreadable" I also do not have any options once I right click on the "Unallocated" area.

I just want this disk formatted and used as extra storage, I did load the Vista DVD and tried to load it on this disk but I got an error as well.

This drive works fine if I put it back in the machine it came from.

Answer:"Unknown" and "Unreadable" disk drive

Install your chipset drivers and make sure you have your SATA drivers installed as well.

Answer:"Unknown" and "Unreadable" disk drive

Download and run the disk manufacturer's utility to partition and format this drive. That should find the drive and do the job for you.

You didn't say what brand of drive it was, so I can't point you to the utility, but you can find it with a search of the manufacturer.

Check BIOS settings for RAID and SATA. It may need to be tweaked.

I have a customized Asus M4A875-M system with:

- Phenom quad core 9750 CPU @ 2.4GHz
- 16GB RAM
- BluRay & DVD R/W optical drives (2)
- 500W Antec power supply
- 4 disks:
= drive 0 - Vertex2 80GB SSD 2.5"
= drive 1 - Toshiba 680GB 2.5"
= drive 2 - White Label 1TB 3.5"
= drive 3 - Seagate 1TB ST31000528AS (just upgraded drive firmware to CC49 from CC45)
= Windows 7 Ultimate
= OpenSUSE tumbleweed linux
= Linux Mint 17.2
= Windows 10
= Windows 7 Home Premium
= OpenSUSE v12.2

My boot loader is grub2 with a nice custom boot menu using this background image.

The issue is the Seagate drive is listed as an "unknown device" under Windows 7 Ultimate OS (along with 3 other volumes) despite the fact it works OK when I boot Windows 7 Home Premium. Haven't gotten Windows 10 to boot yet, so don't know about that, but its just fine under all of the Linux OSs too.

I have all of these backed up using Macrium on a 3TB external USB also.

All of the UUIDs for each disk and partition (volume) are unique as reported by gparted under Linux. Having an issue with Windows 10, but I'm saving that for a separate thread.

The Seagate was showing up OK before the FW and RAM update. I may have confused the Win 7 Ultimate OS when I had to remove the CMOS battery to reset mobo, and I forget to switch the SATA ports to AHCI mode.

A few weeks ago, something changed on my 2-yr-old Dell Vostro 410 desktop running Windows XP SP3.
All of a sudden, the cursor arrow started to also have the hourglass next to it ALL the time, and the hourglass was slowly flashing on / off with a period of about 5 seconds.
When this started, my 250 GB hard drive had ~100 GB of free space. Within a couple days of this weird new behavior, and with no real change in computer usage patterns on my part, I started getting messages that my hard drive was FULL!

I tried deleting some files and programs to free up some hard drive space, but the free space is quickly (minutes) filled and the "Free Space" returns to near zero.
The flashing hourglass is still present, except in Windows Safe Mode.
I cannot connect to the internet using IE.

In Windows Safe Mode, there is a shortcut on the Desktop of the Administrator User that is named "Repair System Registry" and is targeted to Although the "Created" date of this shortcut is a couple weeks after all this started occurring on this computer.

I cannot run any of the First Steps listed in the linked info, because there is no room on the hard drive for the programs or the logs that would be produced. I get error messages when I try to load anything onto this computer. Is it possible to run all these First Steps from an external drive?

Is this a malware issue? A software issue? A hardware issue?

Hey guys, kinda new here, hopefully I'm posting this in the right forum section.

I'm not that super oriented with computers, I'll give it my best shot to explain what's going on here.

In short my PC just won't start. The light turns on, it boots up, and then I get a black screen with text referring to either "Start Up Repair (recommended)"


"Start windows normally"

If I choose start windows normally, it brings me to the black booting screen with the windows flag, then it proceeds to go back and restart the system, going back to the black screen. OR More likely it just stays stuck on the glowing windows flag.

This also occurs if I press F8 and go into safe mode. After listing all the components before going into safe mode, it simply restarts itself and goes right back to the black screen of the two choices.

If I select Start up repair, a grey loading bar appears below that on occasion freezes. If I manually reset the computer try it again, I get to a blue windows default background screen and the message

"Startup Repair

So I will lay out the basics that I know that should enlighten the situation.

I'm currently using a 250GB HDD and it is partitioned into 2 Logic Drives:

C: Local Disk (222GB)
D: Recovery (10.2GB)

I'm using a Home Premium copy of Windows 7 32-Bit OS. So, when I click the Start Menu (Windows Button) and then select "Computer", I can see both of the drives.

The Local Disk (C) drive says "77.7GB free of 222GB"; this changes every so often throughout a daily usage, generally by .5GB - 2GB of used space.

Recovery (D) drive says "5.07MB of 10.2GB"; this is what is prompting the windows messages.

Now what I know:

Your actual physical HDD is split into 2 Logic HDDs, called "Partitioning". Here they are the 2 HDD listed above. The Recovery (D) is used to store your System Image so that you may recover your System to a certain date.

At one point in time this drive was a 25GB and I have no clue what happened; it's possible I might have uninstalled a program with the name "*something* Backup". Anyways, having such low space remaining prompts windows to present messages to alert you.

What I have done:

Windows 7 puts up a little flag that shows you the "Alert Center" in the bottom right corner of the default taskbar. I selected the flag and when to the center and then clicked "Turn of Backup warnings" and that resolved one problem.

Then I went to the Start Menu again and Righ... Read more

Answer:Recovery (D:) Drive prompts "Low Disk Space" Warning. Issue creating Backups.

who makes your machine? i'm guessing they installed software to automatically backup data to this recovery partition. you would have to look up or speak with a support rep about how to create multiple different backups.

what os you running? we may be able to find a different software to accomplish your goal.

My PC wouldn't boot off the SSD (with Win 10 OS). It said there were boot problems and tried to diagnose the problem but it doesn't boot. I'm now using the original HD with Win 7. I'd like to get the SSD working if I can. The SSD is OCZ - 240 GB or so.

But between last night and today, the SSD has gotten worse. I can't access it at all now. Last night I was able to access it as an external drive. What I did in between was a chkdsk of the HD just to make sure it was OK. Then this morning I saw that the SSD had problems.

Disk Management shows the SSD as disk 1, but it has no information on it. It just says the disk is unknown and uninitialized.

I saw a recommendation for Partition Wizard 9.1 Free. But that doesn't show the drive at all. I attached screen shots as a Word document.

Any help would be greatly appreciated.

I have numerous single- and double-sided old 5.25" floppy disks which relate to DOS-based programs I wrote many years ago, and still use today.  I would like to access these disks (for source code, compilers, linkers, batch files, etc.) in order to make modifications to the programs.  I have determined that the drives are still available from various sources, and some even have the necessary ribbon cables included.   I have not determined, however, whether those floppy drive ribbon (or data) cables will connect to motherboards in use on XP based machines (machines which range in age from perhaps three to ten years old).  Before I purchase the drive, I'd like to get a definitive answer to this question.  So - if any of you out there have long memories, or better yet, recent related experience, and can provide an answer to this question, it would be very helpful to me.  If I remember correctly, the old floppy drives had connections from the drives which resemble PCI adapter board connections, rather than pin connections.  My hope is that the older ribbon cables use the same pin connections to the motherboard as more current 3.5" floppy drives.  Maybe there's even a way to rig an external version of a 5.25" drive to work just long enough for me to convert the old disks to CDs.Thanks very much.

I have four external drives (FAT32) and opened Partition Magic a couple of days ago. It said one drive was "BAD". MS Disk Administrator says drive is "Healthy".

I am able to access this drive through Windows Explorer and do anything I want with the data. This appears to be a false reading by Partition Magic but I am not completely convinced of this because it has been such a good program for many years.

Do you think I have a failing drive?

Answer:Partition Magic says drive "BAD". Disk Administrator says "Healthy"

I wouldn't trust either program. Find out the manufacturer of the hard drive and download their hard drive diagnostics. The manufacturer's own tests should give you a much better idea if its in good shape or not.

Hi, I'm new to the forums. I had 2 paritions on my other (main) computer which were one 75 gigabyte partition which was my primary partition with the OS (Windows XP) installed and a second one which is 5 gigabytes which I previously had when my computer was bought. The 5 gigabyte partition is on the same hard drive and it had no files in it when I partitioned it using the software Power Quest partition magic. It said that everything went fine after it merged both drives and it said press any key to restart. So I pressed a key and it restarted but soon it went to a blank black page with the blinking bar on the top left. I waited for an hour and nothing loaded so I pressed the power button and it IMMEDIATELY shut down. When I restarted my computer it gave me the error "Floppy Disk(s) Fail (40)". I tried to enter BIOS setup and disable the floppy disk drive, change the bootable disk list and changed the first boot option from "Removable" to "Disable" because I assumed it wouldn't check for the floppy drive but it did.

I have been trying to transfer my "favorites" from my old computer (windows 98) to my new one with windows XP. When I copy the favorites onto the floppy I can see that they are all there. BUT, when I put that floppy into my new computer it changes the favorites contents to those on the new computer. For instance: I had probably 100 sites to copy and my new computer favorites only has about 10 sites. Now those 10 sites are on the floppy and not the 100 I placed there.....I'm confused.

Could it be that I just need to create another folder with a name like "misc" and copy the favorites that way...not using the name of a folder already in windows XP?

I could burn the favorites onto a cd too, I know that, but I wanted to see if a floppy could do the job first.

'Found New Hardware - USB Floppy Drive' then 'Cannot install this Hardware, There was a Problem Installing this Hardware Y-E Data USB Floppy, An error occured during the installation of this device, The Specified service has been marked for deletion'

Then I went to the Toshiba website to see if I could download any 'floppy drive' drivers and it didn't bring up any, when I selected 'all drivers' it brought up 45?

I'm using Windows XP Professional! Really appreciate any help.

I have a new Lexmark Pro200 series wireless printer. I have it installed on our home wireless network and can print to it fine from two separate Vista laptops. On an older Dell XP (SP3) desktop machine, however, when I try to install the Lexmark printer drivers from their CD, I get an error. The full text of the error is:

"Failed to create print object Lexmark Pro200 Series (Network). The specified port is unknown."

The error appears near the end of the installation process. Also, no printer icon shows up in Printers and Faxes

The first thing I did was contact Lexmark technical support. They tried several things but to no avail, including doing an uninstall and cleaning of any Lexmark drivers, disconnecting and reconnecting the printer via a USB cable (not needed for normal operation), and reinstalling the drivers a couple of times. They said the cause of the problem is something wrong with the Spooler Subsystem Apps and that I would need to repair or update it.

Any ideas how to do this? I've got some decent tech skills and am comfortable doing minor tweaks in the registry and such.

Help - Please!!!  My Desktop decided to install the Windows 10 updates to my Windows 7 environment -- oh the joys!  Nothing but trouble ever since.  I uninstalled 10 to take me back to 7.
Upon reboot all was fine for a day.  Then, black screen with a cursor.  What the heck?  I checked all the things I was told to check, I ran all the diagnostics.  I uninstalled, reinstalled, did a system restore back to before the update.
After spending 3+ hours letting my system go thru the recommended ePSA Preboot System Assessment (All Tests Passed) - Today I have a system that I can't get to boot up because it says I have:
Status:  Oxc000000f
"The boot selection failed because a required device is inaccessible."
I'm not a computer geek.  I can't get thru to anyone at Dell.  I've been trying to resolve this for 4 days now. 
The only thing I can think that is happening is that the computer is trying to boot from an external hard drive that is in a "locked/password protected" mode on my system.  I have no idea how to bypass this.  I've tried unhooking the drive and rebooting and then it just goes back to black screen with a cursor.
Can anyone help me?  Please?

IBM ThinkCentre A50 8320-7EG, Windows XP

Just reformatted and reinstalled, lists the ethernet, audio and video as 'unknown devices' (ethernet at least definately worked fine before reformat). All integrated with the motherboard.

Have tried to install drivers from the disk, downloaded from the IBM website and from driver packs but nothing has had any effect, using the wizard it won't recognise any drivers, installing the alleged drivers manually it says they have installed on the installation wizard thing, but nothing's changed with the device in device manager.

I assume somehow I must have the wrong drivers, but not sure how this could be the case, or really what else I can try.

Thanks very much for any help!!

Most applications that allow you to "save" something still use the floppy disk to symbolize this, which IMO is out of touch and outdated.

Obviously, for people who are used to computers, it doesn't matter what the icons look like. But for newbies, the icons and symbols are meant to make it easier and more logical to work with otherwise complex tasks like file management. That's why we have icons resembling folders, sheets of papers, photo frames, envelopes etc. In about 1996, letting a floppy disk symbolize "Save" made sense. They were incredibly common for storing as well as transfering files. At many schools and offices, you would bring your own floppy disk and save everything on that instead of using the hard drive or a server. But today? Anyone not born in the 80's, or someone just starting to use computers now, has probably never actually used a floppy disk.. Isn't it time to replace the icon with something more modern and relevant?

Answer:The "floppy disk" icon

This is a good point and one I'd never really thought of before. GNOME uses these:

First time posting here, so I apologize if I my post is too vague.

I started up my laptop (Alienware M14x, Windows 7 64 bit - not sure if it's Ultimate, Home Premium, etc...) yesterday and it displayed a message saying that Windows had failed to boot. I restarted and attempted starting it in Safe Mode and from the last good configuration and both failed, leaving me with the same screen with the two options of starting normally or running startup repair. I also tried disabling driver signature enforcement, which also failed to resolve the issue. I then ran startup repair and just let it go for about 8 hours and it just continuously "attempted to repair." I left it overnight and then let it keep going for most of my day today. Altogether, it was running startup repair for around 30 hours.

I forced a restart and made a system repair disc using another laptop (also Windows 7 64 bit). I booted with the disc and hit next on the language/country menu. Windows 7 showed up as a choice as my operating system, but I could not hit the next button (blue loading circle would replace my cursor whenever I dragged over the window). After a couple minutes, a window appeared that said something along the lines of "identifying disk." This window stuck around for about 5 minutes and when it disappeared I was taken to the system recovery options. On the top of this window it says "Operating System: Unknown on (Unknown) local disk."

My Dell 4600C's XP op sys was eaten by a virus before Christmas and the local shop wanted more than I have to reload XP, the backed up data and get me going again. They did say the hard drive was functional and fine. I found instructions on getting rid of all existing partitions before reinstalling XP, and have come down to the end of the installation and stuck with the error msg above.

I've read through J Barnett's instructions to load Windows onto a SATA drive at one of the links provided at the Setup cannot continue thread, and other info at other links there; I will go back through the installation and stop at the prompt to press F6 and install SCSI or RAID drivers. But I'm not completely clear on how to find the drivers on the cd's I have. I've opened up the case, made sure cable connection is tight at drive and board, and now know I have a WD400 Caviar drive - that came with the Dell.

Have been to Western Digital site to look for drivers for my model number and found specs and jumper settings for the 400BB, but the list of downloads is greek to me. There are two that mention IDE/RAID compatibility upgrade - one for 3Ware cards and one for Non-3Ware cards. Help??? I thought I just wanted plain ol' drivers.

Alright, so I bought a new portable harddisk, the samsung 3 1tb. However for some reason my pc does detect it, but is not able to run it. it gives me the error that it is an unknown device.

However, i tried the Hdd on several other pcs, and it worked fine, leaving me the conclusion that my pc is at fault. After recommendations from a friend, i tried to find myself some updated drivers for my motherboard, specifically usb drivers. However, my driver CD, aswell as the Asus site did not support my operating system (Windows 7, 64 bit).

So here I am, still unable to resolve this, hoping that any of you might be able to help me out. If you need any additional information, ill provide it asap.

I have Norton Internet Security 2004 installed and I think it may be that the AntiVirus keeps scanning the Floppy Drive. I am not sure on how to disable scanning the Floppy Drive and if someone knows how to do it could you please instruct me on how to disable it.

Hello everyone,

I am pretty good with computers and stuff, but I have been having a problem now for a few months trying to boot up an old 486-DX 100 HMz computer.

It is a hack computer, with rogue parts making it up. It used to work great when I set it up for my little sister to do school work on, but now it is goofed up. Real bad.

Its gutted right now, just a motherboard and power supply, etc. I have 2 seperate Winbond IDE controller cards, one of which I just picked up tonight while getting a brand new Flopp Disk drive. A few of the primary specs of the new controller are:

Winbond IDE/Floppy Controller
Winbond Chip - W3758P

Data Technology Chips
DTC2278VL and DTC-805

The old card is an almost exact duplicate, differing in that it offers two IDE pinouts rather than one

I have been thru the BIOS extensively, and it should realistically be working just fine with the specifics entered. It is an AMIBIOS 1994 model. Specs as follows:

AMI 486 Vesa Green Bios (v. B)

Processor gives a screen output of:
i486 DX 4 - 100 MHZ CPU

Ok, so heres the problem (if you have made it this far, thanks).
I am trying to get this thing up and running again. I know the motherboard is in good shape, and I have a good idea that my IDE cards are as well. When I turn it on, however, the Drive Light stays on, and the cylinder rotates to no end. I have a brand new Dick Drive, and am getting the same problems.

If I switch the input of the Floppy Cable (flip it around) the drive stays idle, as if ... Read more

Answer:Floppy Drive - Light Stays "On", while Cylinder Spins - Can you help?

Alright, Id like to thank absolutely nobody for even looking at my thread! However, as usual, I have used the awesome power of my incredible brain, and found my own answer to my first question.
Now I have a second. I am using an old as f-uck floppy cable. So old that in fact, it has the card slots for 5 and a half inch Drives. The slots are throwing off my BIOS, automatically taking the place of Drive A. In turn, i must assign my Floppy to Drive B.

My BIOS Options do not have the possibility of setting a boot sequence for B, C or B, A, C or anything else. Only A, C or C, A.

I doubt any of you would know, but can I get away with cutting off the old card slots on the cable? Since noone has posted any replies to my last question, and from what I have gathered from scouting old posts, I assume noone knows. Im probably dealing with some amateur-at-best class programmers.

I know someone on here has to be Nerd enough to know. And Nerds not an insult, so dont go gettin all uppity, please. Im plenty freakin Nerd myself!

I apologize if this is on the wrong place in the forum, feel free to move it. Here's my problem.

I am using Windows XP Home. Recently the floppy drive seemed to quit working, but device manager says it IS working.

The problem is whenever I try to use a floppy disk I get an error message saying: "a:\ is not accessible. No ID address mark was found on the floppy disk"

It doesn't matter which floppy disk I try to use...NONE of them will work. It happens even if I put in a blank diskette.

I have not made any changes to my system or done anything else that I can think of to cause this.

I tried unisntalling and reinstalling the floppy drive device driver, which didn't make a difference.

I also tried reformatting a diskette on another XP computer (full format not quick format), then placed a .txt document on the disk. On THAT computer it can see/read the floppy and the text document just fine, but not on MY computer. Whenever I insert the floppy and try to do anything I get the same error message above.

My computer's tech support said there's nothing they can do since the floppy drive IS working.

Can anyone help? Please?

Answer:No "ID Address Mark Found" Floppy drive

The PC can only "see" as far as the interface to tell you the device is working OK.

It cannot tell if the head has died or the drive is out of alignment.

Needless to say, the drve was online and contained LOTS of data before the crash. Due to it's size, the drive was GPT.

I cannot get the wired ethernet or wireless working at all on this laptop. Under the Device Manager, the Broadcom 440x 10/100 NIC and the Intel Pro/Wireless 2200BG are both under "Unknown Devices". There is no "Network Adapters" like there should be. While it looks like both drivers are installed correctly, Windows doesn't recognize them as network hardware. There is nothing under network connections. I tried uninstalling the drivers from the Device Manger and restarting and XP just reinstalls the drivers and puts them right back under "Unknown". I also tried a system restore to when they did work and they still don't work now.

If they show up as unknown..the drivers are not installed correctly. Remove them...get the proper drives for'll probably have to transfer those drivers over using something like a USB thumb drive. Follow the instructions on installing those drivers.

Ok first off I want to say I've searched and searched and searched to no avail in trying to find a solution to this I've come to the conclusion it's software and not hardware based. Let me start from the top.

I've had an older computer (HP Pavilion a408x) out of commission for a while due to a 'sploded psu. I finally get around to ordering one, install it and everything is good. I bring it back to my office and hook it up to the internet and as expected there's updates. So I up date it and after the updates are installed the computer restarts automatically (weird yes) and as it's coming back on it detects errors and runs CHKDSK. So I let it run and it gets to part 2 of 3. At this point in time my partner is really needing to print sometime and all computers print through this computer. So after about 45 minutes CHKDSK is still on part 2 at only 15%. So I'm like "screw it" and manually shut down and restart. It's at this point I get a "primary master hard disk failure" at the boot screen. Letting start up continue I get a "Stop : c000021 unknown hard error \systemroot \system 32 \ntdll.dll" At this point I realize something is delectably wrong.

Found this thread, which didn't help much. At some point the c000021 error stops and I start getting "disk boot failure insert system disk and press enter" and I found this thread, which didn't help much either. I have also been searching other sites as well.

Sorry for a long post, but the problems have been mounting and I want to be clear with what's wrong...A while ago my computer stopped functioning. After playing a game, I left and came back to find the screen black, so I hit the hard restart button, and it got to the screen with the Gateway logo but when that ended and it should have flashed to the Windows Loading screen, it just went black with a blinking white _ . I tried hard restarting several times, and each time it would go to the black screen with the white blinking _. It shows the BSOD. Even trying Safe Mode only got me a little bit farther - I could get past the gateway loading screen.Finally I decided the best thing to do would be to reformat.

Here is the screenshot from Disk Management

Answer:How to delete "Unknown Disk 3"

Really don't know what is happening and in the circumstances shoot all around in dark

1.Make sure you do not have any USB storage device connected to the front and rear ports. Sometimes a faulty pen drive can show up as an HDD..

2. Open Device Manager and check the disk drives shown. Also examine under USB for any unknown device.

3. No clues? Try Power cycling your PC. Remove all externally connected devices (except your Key board and mouse), shut down your PC and disconnect it from Mains pulling out the power plug. Leave it for about five minutes. Press the power button repeatedly a few times and hold for a few seconds to remove all charges in the PC. Power your PC now and boot.

Does your PC still show Disk 3 in WDM? Right click on Disk 3 icon on the left and check what Menu items you get and also check what it says when you try to initialise.

On my wife's computer running Win98SE.

I am trying to update the keys to my Kaspersky Anti Virus program (so I can update from the internet). In order to do this I have to un-install the program then "attach" the new keys. Usually this is not a problem, I have done it before.

However, now when I try to un-install (KAV), as soon as I click to "uninstall" the A: (floppy) runs for a moment and the un-install progress box that popped up goes blank.

Another thing, if i try to simply install the Kaspersky Anti Virus program from my D: or E: drives (CD) the program responds OK for a moment, the floppy "runs" for a moment, then I get a message something to the effect "original source files not available".

I suspect the problem is something I have done, but I don't know where to look.

Answer:Floppy drive "runs" to much?

It clearly thinks that the KAV program was installed from a floppy. Try putting in any old floppy disk and see if that then gives you the choice of pointing to the correct location.

As a part of regular maintenance, I use Glary Utilities and CCleaner to keep the PC clean. In an effort to protect deleted data, I run the "drive wiper"/"wipe free space" function of these programs every so often. I have never had a problem with carrying out these actions until the other day. CCleaner acts like it does something, but having done this before, I know that it's not a few minute operation. Glary Utilities gives a more reasonable response when trying;

"Error: Cannot Wipe free space for UNC drive"

I don't know much about UNC or why my C:\ Drive would be categorized as this. I am on a home WiFi connection, however I haven't every had this connected as a network computer, and also have all of the network/sharing options disabled. I have not made any recent changes that I can recall which may have caused this.

Does anyone have any ideas as to why this may be happening, or better yet, how I can revert back to where I am able to use this feature of the programs?

All input and suggestions are welcome, I appreciate it very much!
Thank you

Answer:Unknown reasoning for "Error: Cannot Wipe free space for UNC drive"

Hi redhatman, welcome to 7F!

Sounds like something happened when CCleaner (CC) attempted to wipe the free space, Glary picked up on those changes, and it ended up being a UNC drive, and it (Glary) couldn't determine the original working directory to start itself.
Did CC show the "Cannot Wipe free space for UNC drive" error?
Had you made any changes to the file system between the time you last ran CC?

What to try:
Before every CC run the program asks you if you want to create a backup of the registry, if you were prudent enough to do that, try running that backup. https://Problems after you have run CCleaner |
If you made a restore point try it or the closest one to before the time/date of this wipe.
Start your machine by Last Known Good Configuration. See Step #4 and use your arrow keys to move to that option.
If all the above do not work you may have to try a Repair Install.
As a last resort try backup images or clones if you have them.

If any of these steps resolves your problem you should run a CHKDSK, and SFC /scannow.
By the way, thank you for filling out your System Specs; If you add the model number (K60IJ) of your laptop to your System Specs you won't have to list it or the rest of them in any of your subsequent posts.

Today, my notebook crashed (BSoD) while playing an online game - Team Fortress 2. It happened a few times before and, with a little research, found that other users with my video card had the same problem, so I thought nothing of it. After the most recent crash, on reboot, I get the message that "NTFS.sys is missing or corrupt," and I can't access Windows at all. I can get into BIOS fine.

I tried using the Recovery Console to copy NTFS.sys to my Windows\System32\Drivers folder, but Recovery Console isn't recognizing any files or folders on my C: drive. When I enter the DIR command, I get the message "An error occurred during directory enumeration." If I access the D: drive, my extra partition shows up just fine, and I can access all the files I've stored on there.

When I boot with my Windows CD and look at the partition information, I see the following:

-: Partition1 (EISA Utilities) 4997 MB ( 355 MB free )
C: Partition2 [Unknown] 54486 MB ( 54486 MB free )
D: Partition3 (Storage) [NTFS] 54988 MB ( 1141 MB free )

Although the count and free space for drive D: is accurate, drive C: isn't even close. The total is correct, but the actual free space is around 8-10 GB.

Here's my setup:

Acer Aspire 5050
AMD Turion64 x2 (1600 MHz)
ATI Radeon Xpress 1100

My Granddad gave me a computer last year, and when I got it it had 35gb of 64gb filled up already.

I looked for the files taking up all the space for a while but could never locate them, so I gave up and went on using it with only half the HD actually usable.

Move on to today, I'm starting a solidworks class and I need the free space, but I can't find where the files are for the life of me. I tried to see if there was some partition, but when I went under device manager > to the Hitachi hard drive properties it showed a - next to partitions.

How can I delete this unknown file?

Here is a screen shot of a program showing HD usage.


Answer:"unknown file" taking up 29GB of hard drive.

Go to Start/Run and type diskmgmt.msc and hit enter. In the Disk Management Console you can see if this is a separate partition, like a Restore partition. If it is, you can format the partition but you will loose any chance to Restore in case of disaster. If you really need more space, it would be safer to buy an External USB HDD and store your files on that.

I have used WinDirStat to verify they are there in limbo, and then used file scavenger to actually identify them.

It amounts to me having had a virus and reinstalling my OS. When I did, it left the original C drive data in tact and started a whole other separate area for the new OS. For instance, my entire itunes library is there - some ten gigs. In fact, when I reinstalled itunes, it somehow read the original library but did not have access to the files (exclamation point next to each song). So somehow it had access to the listing, but not the files themselves.

But I CANNOT, no matter what I have tried, get to the previous files and delete them. There is still only one C partition, it did not create a new one.

I have tried file shredder as well as WDS to clean them up - but all the clean options are grayed out. I have also disabled and removed all restore points. I have tried these things in safe mode as well.

HALP!! I dont wanna do a completely fresh install if I can help it.

Thank you in advance.

Hi guys, using Windows 10 Home, 64 bit.

Never before in my time of using Windows computers have I seen this before. Today, as I browsing through my files, I noticed in the left pane of the Windows Explorer window that another "hard drive" or, for all I know, "partition", has appeard in the list of available disk drives. It's name is "SYSTEM (Z" and I have no clue how it got there. It's a 356 MB file system, FAT32, defined as "Local Disk", and apparently has about 75 MB already used. I tried looking at it using diskmgmt.msc and it shows it as a 360 MB partition in my main drive that is hosting the OS. It is NOT the recovery partition. It also doesn't have the aforementioned "Z:" designation that the Explorer displays. It also, as you can see, doesn't have a name, either. See attached photo:
Here's another look at the main drive using EASEUS Partition Master. This time, the actual name "SYSTEM" displays itself:
Anyone know why this is showing up? And can I just delete the partition and merge the free space? Or will that mess up any OEM factory install stuff? I want OEM files to remain. I just know that this WAS NOT here earlier.

Does anyone know?

Answer:Unknown drive appearing in File Explorer, "SYSTEM (Z:)"

Below is what I wrote in another forum when a poster asked a similar question. It's very late at night here and I'm just about to go to bed, so decided to cut and paste what I wrote there, changing the necessary details. Whatever you do, don't delete that partition. Below is what I wrote on how to hide that partition (remove its given drive letter).

That's your EFI partition, which is the partition used to initiate the booting process of the OS(s) you use on the machine. It's normal that the partition exists and you shouldn't, unless you know what you're doing, mess with it. Still, it shouldn't really have been made visible and given a drive letter.

Why it got a drive letter is a bit of a mystery. It happened to me when I upgraded from Windows 8.1 to 10, but I fixed it using Windows own diskpart (Disk Manager wasn't enough to solve this). Is it harmful to keep it as it is? Not really, but it's annoying that a drive letter gets taken by it.

The following might be daunting, so do this only if you feel confident, but it's not that difficult if you follow the advice to the letter. I can't stress this too much, but backup your system with a backup utility or, at the very least, the files you deem important. The EFI partition is critical and if broken will make your machine unbootable, so think seriously if you want to carry on.

Recently my nephew's netbook has crashed. Windows 7 Starter would not load. I tried a few fixes which proved unsuccessful. Right now I am trying to install Windows 7 but am having much trouble. When the setup screen loads up and asks me to choose a partition the following items are present: Disk 0 Partition 1:RECOVERY, Disk 0 Partition 3: SYSTEM, Disk 0 Partition 3: Primary (40GB), Disk 0 Partition 4: Primary (178GB). It will not allow me to install to either Primary partition with the following reason: "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu.". I have also tried to format both the 3,4 partitions but always get an error message, although the one that had windows on is now showing nearly all memory space free. I would appreciate any help that could lead me in the right direction so I can get Windows 7 Starter installed on this computer. Thank you.

Answer:Trouble Installing Windows 7 "cannot install to this disk"

Have you tried running Factory Recovery from its partition? Tap the key(s) given to trigger it on first boot screen or in the User Manual for your model.

Try also deleting the last three partitions during booted Custom install using Drive Options: Clean Install Windows 7

If this fails try creating a Primary partition there and marking it Active using Step 2.2 here: SSD - HDD Optimize for Windows Reinstallation

If install still fails, wipe the HD using the above tutorial and try install again both with and within pre-partitioning. Note that the Recovery Partition will be deleted if you do this so make sure it is not working first.

You can do the operations in the last two paragraphs with a graphical interface using free Partition Wizard bootable CD.

About 3 hours ago I installed Windows XP x86 on an empty partition. Before the install my partitions were like this:

C: Windows7
D: Empty NTFS Partition
E: Backups Partition

I've installed XP many times before and I've never had this happen, but when the install finished, suddenly my Backups was C and my Windows 7 partition was E, making Windows 7 refuse to start. I tried to go into XP and switch them back to their original letters using "Computer Management" or something similar under "Administrative Tools", and to do that I had to make the Windows 7 one "active" and switch the letters, but it still wouldn't start.
The Windows 7 install disk will sometimes detect something is wrong, but it's tried to repair it 3 or 4 times now and still the same thing: "A disk read error occurred, press Ctrl Alt Del to restart".

I have a T60 laptop with a 55 Gig hard drive and only 350Mb of free space. I ran WinDirStat and it shows an "unknown" file taking up 30 Gig of space. I am not sure what it is or what to do about it.

I cannot find it (the "unknown") in Windows Explorer (I "un-hid" the hidden folders, etc.).

Has anyone run into a situation like this before?

Any advice?


Answer:"unknown" taking up space on hard drive

Did you personally setup this machine. i.e install Windows etc? 30 gigs sounds like an Operating system i.e linux. Windows cannot see a Linux/Bsd/Beos etc partition.
If you get hold of a Linux Live Cd it usually has Gpart(Like Partition Magic) on it . Gpart will tell you what is there. It can also reformat it to any type of media you want.

I just installed a new 80 GB Hitachi hard drive into my HP Pavillion PC running windows XP Home edition (sorry, not sure of the exact model, I am at the library.) I originally installed the new HD as a slave drive where I copied all the files from my old HD (I had received a SMART warning of imminent failure.) After the copy was complete (using the included software, OnTrack) I was instructed to reboot and place the new hardrive in the Master position, the old in Slave. I originally tried to boot without my old one in at all and received an error "Remove disk or other media, press any key to restart". There was no disk in any of the drives. I have tried rebooting with my old in as slave, to no avail. My computer still works when I install my old harddrive back into the Master position, but will not work at all with the new drive in as Master. Any help would be greatly appreciated.

p.s. In case anyone was wondering I did check the jumpers on the pins of both harddrives and have switched them every time accoring to the configuration I was trying. The floppy drive, with the old HD, does work, as do all other drives. When examining the new drive all the files have been copied. Seems like a BIOS or hardware issue. I am calling Hitachi tommorow if this is still an issue.

Answer:"Remove disk or other media" after installing new HD

So you just copied everything over and didn't install? I'm not too familiar with booting protocol but the fact that you didn't install a new operating system is different than if you just copy an operating system over. If you still have all of your stuff on the original drive, put the hitachi in as master and boot with your xp home cd or other recovery cd that came with your computer. If you want to install a new master hdd then you have to reinstall an operating system. If you don't have a windows boot disk or other recovery boot disk and you purchased your pc legally and new, you could probably get HP or Microsoft to send you a copy since you own the rights to it. As far as I can tell nothing is wrong with your new HDD yet.

Answer:Problem: "Disk Boot Failurs, Insert System Disk and Press Enter"

If you're running a HP what it's asking for is your System Restore Disk. Meaning the HP OS that came with your system. Finding Bios in HP are generally simultaneously with Start button on casing F1 or F11. If neither key works then try F2 and or the Delete button. Making sure each key is pushed as you boot up.
Once your in Bios use the arrow keys to scroll up and down your bios - the enter key once on the various listing in menu until you find your boot sequence listings. In general plus and minus are used to change the sequence. CDrom HD and floppy is the correct setting. But with your Restore Disk from HP it might not even require all that.
Pop it is and Boot up and see if it works. Then try the Bios sequence if you can get there, the F10 to save and enter making sure your CD with the OS is in your CDRom when you do.
Let us know as things go...Jazz
Sounds like you've either lost your OS or you've lost your HD.

I just received my new laptop yesterday with the full intention of removing the Windows 8 installation and installing Windows 7 Ultimate 64-bit. After some work with the BIOS screen I finally made it so that the Optical Drive was first in the boot order but now I can't get it to run the Windows 7 setup.

1. Turn on computer.
2. At prompt for "Press any key..." I hit a key.
3. The progress bar for "Setup is loading files" completes.
4. The screen comes to "Starting Windows" and the MS log comes on to the screen.
5. Nothing further happens, the screen remains with the MS logo and "Starting Windows"

Windows 8 boots without issue (but I don't want to use it). I tried reading through a number of other threads but they seemed to be dealing with desktop PCs where hardware was easily removed. I have never had an issue with installing Win7 from the DVD before. I have already tried removing one of the memory chips but that did not resolve the issue.

Comp Specs:
Asus A55A-TH51 (purchased from tigerdirect)

I thought this would be an easy change as it always has been but I really need some help with this one.

Answer:Issue Installing Win 7 Ult x64 on New PC; Stuck @ "Starting Windows"

On a Windows 8 PC you likely have to turn off Secure Boot in BIOS setup first before you can install Win7.

Then you need to follow special steps to boot installer to install Win7 using UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

All of this is detailed in Downgrade Windows 8 to Windows 7.

Some users decide not to mess with UEFI but to instead install normally to an MBR disk as shown in Bypass UEFI to Install WIn7

I'm hoping this is a simple fix. I'm trying to fix my elderly uncle's Asus laptop. System Repair pops up and fails. I booted to command prompt and found out it may be hard disk space. 400+ GB Hard drive (only one drive) and there's only 1024kb Free. I'm thinking that could be the issue. Hardware was checked out at the computer store and is fine. But they were going to charge him $200 to fix this failure to boot up issue. I told him to let me try first.

Can I possible "compact" this drive from the command prompt screen?

Note: I have no other Win 7 systems, so can't create a disk, and I have no original disks.
Also, no restore point has ever been set, and there are no partitions on the drive.

Answer:"Startup repair" failing - hard disk space issue?

Normally, I'd tell you to download a program or two to examine what's using the space or to clean up unnecessary files.

But with only 1024 kb of space, you probably can't install anything.

So--try this:

Start button, search box, type in "disk cleanup" and then poke the disk cleanup listing that shows up.

Let it clean up the drive and report back with how much space you then have.

You'll see an option in disc cleanup where it asks if you want to clean up system files as well. Say yes.

It should calculate how much space it will recover.

Let it run to completion. Might take a few minutes.

Then check your recycle bin to see if it's empty.

Report back with available space.

Hello, everyone. I'm new here and the only reason I was forced to access this forum is because of the multiple and continuous BSOD's i keep receiving. I upgraded my system and also upgraded to Windows 7 Ultimate (x64) from XP SP3 (x86). I did a clean install: formatted my 20GB partition and installed Win 7 (with both sticks of RAM installed). Installed available updates for Windows + all my necessary software. So far, so good. I don`t remember exactly when (the next day, I guess) I started receiving BSOD's. I tried multiple settings in BIOS: tried everything on Auto, tried increasing RAM voltage, tried setting the default XMP profile for my RAM... same results, same BSOD's: dumping phisycal memory to disk.

Tried a different approach: did another fresh install... same BSOD's. Then tried installing ONLY Windows updates (the important ones)... same BSOD's. So that rules out driver issues.

I have 0503 BIOS version and when I tried to update to the latest 0504 from AsusTek official website, I received an error: boot (something) doesn`t match, or something like that. Anyway, they state out what is fixed in the 0504 version and I don`t think that fix might help me.

In Windows Explorer, with a Sims disk in the drive, double click brings up the error message: E:\ is not accessible. The disk structure is corrupted and unreadable.

In Disk Management the CD-ROM drive shows. I can change the drive letter. It shows "383.58GB RAW"

I ran the Microsoft Mr Fix It - Mats/DVD.RUN and it found no issues.

I Removed the Drive from Device Manager and restarted. It installed the same garbled device. There is no Roll Back Driver. There is no Update driver.

The only thing that she thinks was changed was she installed 3 Windows Updates that came through today. But I did a System Restore to before that install and no change.

I have not done anything new to my computer in recent days, so this problem has caught me off guard (I see most instances of this problem come after upgrading to Windows 7, I have had Win 7 installed for a while now).

Here is a summary of my problem:
1) My computer recently got stuck on the "Starting Windows Screen." So I manually held the power button to reboot.
2) On reboot, it said there was a need to run a startup repair, which I did. Everything checked fine, except for the last one which said "System Volume on Disk is Corrupted," which it claimed to have successfully fixed.
3) After rebooting from repair, the system gets stuck on "Starting Windows Screen" for a good 10-15 minutes, after which it runs a registry check. After it completes that I get hopeful -- but the screen then gets stuck on an all black screen with just the mouse cursor and nothing more.
4) Additional note: Attempting to start the computer on "safe mode" leads safe mode startup to become stalled on "DRIVERS\CLASSPNP.SYS"
5) The lastest attempt to repair yielded this message: "Startup repair cannot repair this computer automatically.

Answer:Stuck on "Starting Windows", Repair Shows "System Volume on Disk is Corrupted"

Hi Stan, Hopefully I can help you out....or at least lead you in the right direction. From my experience, the symptoms you are suggesting sound like perhaps a dying Hard drive.

1. Do you have the windows 7 boot disks that came with your computer or when you bought the Operating System? If so, you could try and insert one of those and boot from it, and attempt to repair the installation. (this won't affect your data, only the windows system files).

2. If that doesn't fix it, you could try a fresh reinstall of windows 7, and see if that works.

3. If neither of those work, its likely that because of the fact that when windows is repairing itself, it is generally putting copies of its system files in the same physical location on your disk. Because your disk is obviously not completely dead, ie....its still loading to the windows 7 startup screen, its just copying files to the bad sectors on your hard drive and gets stuck when loading. This is especially my guess because you said Safe mode is having same problems, even after attempting to repair. In the past, I've tried and salvage a disk by reformatting it and only leaving on partitions which do not contain the bad clusters. This takes some time, and some guess work.....and really this is only a "bandaid" fix because once the disk has bad clusters, its only a matter of time before these things give out. You wouldn't want to trust your important data on it anyways....

I hope this leads you in ... Read more

I have recently updated to the creator version
My files end up in unintended destinations. When I click in the documents tab in the sidebar of the documents screen, it takes me to a ?Documents? folder that appears in ?One Drive? group. Any files that I send from my desktop end up there
Those files are also shown when I open the first ?Documents? folder that appears in the ?Quick Access? group. I have similar problems with ?Pictures? folders
I have attached screen shots that I hope will explain. I want all my files of any description to end up in the ?Documents? folder contained in the ?This PC? group. Can anyone help please?
Incidentally, I don?t understand the purpose of ?One Drive?, and don?t believe that I will have a use for it. Can I remove/disable it?

To start with i am trying to change the name or label (C:, D:, E of my drive.
Reason - I have a portable external drive that i use at uni and home, but the computers at uni label it as E: drive where as the pc at home labels it as D: drive. I am unable to rn applications which i install onj this portable drive with the intention of running them anywhere. But some apps wont run due to the labelling confusion and i have to install them again via the internet on the portable drive again on the new pc.

So I am trying the change the name of the CD drive (at home not uni as the i cant access administrative tools at uni and moreover its easier this way) which is currently labelled as E, so that the portable drive can be labelled as E (just like the labelling at the uni). (btw my portable drive is either labelled as D or any other variable depending on whether i have another usb connected or not. If so, the portable drive gets labbeld differently if connected after the usb, but never mind that)

so i researched online and found that i can change labelling in disk manager.
source - Changing Drive Letters in Windows XP

However, i cant access the "logical disk manager".
Error - "the dependancy service or group failed to start"
Error - unable to connect to disk manager service

So i searched again and followed the advice on this thread

Howdy folks

I'm stuck in a bit of a weird situation here that I have no idea how to fix.
I just bought and installed a new hard drive for the purpose of doing a RAID 0 configuration with my old drive. The BIOS picks up the new hard drive perfectly, and it's being recognised in Disk Management.

See, the pickle here is when I try to convert my Disks from Basic to Dynamic, I get this little epitome of frustration:
Google's not co-operating with me on this one, I can't find a single relevant article.
Is there any way to change the ever elusive 'pack name'?
Anything even slightly relevant will be a relief to read by comparison, so don't hesitate to recommend anything.

Answer:"The pack name is invalid..." - Disk Management Issue

Hi, Modus Operandom, and welcome to the forums.

You say convert it to RAID - but I am puzzled as to why on earth would you try to do that in Disk Management? Are you attempting to use Software based RAID?

A friend has an old Pentium 1 HP Vectra 500 PC. On startup it says "Invalid system disk" like if you had a disk in the floppy drive. There is no disk in the CD or A drive. I took the A drive and CD out of the boot sequence via the bios and it made no difference. Is it the hard drive?

Answer:"Invalid system disk" error w/no disk in drive
