Windows 7 Disappearing From Hard Drive
Mar 22, 2011
I have a custom machine that I just recently built a few months ago. Last week, I decided to upgrade the mobo so that I could have more ram slots and a second PCI Express slot. I swapped out the mobos, booted the computer, and everything was working just fine. The only problem is that I'm running Windows 7 OEM and I've heard that you can run into problems when swapping out hardware. My computer was working for about 24 hours after installing the new mobo but at one point the other day the computer just shut itself down. I went to boot it back up and all that popped up was BIOS. I inserted my Windows disc to try and repair my system and I came to find out that my Operating System, along with everything on the Hard Drive was GONE. I have never heard of such a thing happening. So I reinstalled 7 and basically had to start over from scratch. Another day goes by and the same thing happens. This is now the second time I've had to reinstall Windows 7. My computer is running fine now but I am afraid that this is going to happen again so I'm reluctant to put anything on my hard drive until I know this issue is resolved. I contacted MS but they aren't much help as I only have the OEM version of Windows.

I upgraded from Win XP to Windows 7 64 bit about a month ago (I did a clean install as I've always had issues with in place upgrades). My machine has four hard drives total, two internal SATA drives, and two external USB drives. For some reason my secondary internal drive, a WD 500 GB SATA drive (nothing fancy), keeps disappearing randomly while windows is running. This started about a week ago, it ran ok for the first 2 weeks or so.The drive comes back fine and dandy if I completely shut down the machine and then boot it back up. The drive stays until some random moment when Windows doesn't see it anymore. Now, if I do a simple Restart the drive doesn't show up, ONLY after I shut down completely, and push the power button back on, does this work. There is nothing in the System logs, no error messages, nothing, it just vanishes and is completely random.

A computer has a 1TB drive as the boot drive (C. It had 800GB of files on it. When the user booted recently, most of the files were deleted from the hard drive. I installed the drive in another computer, and the files show up as deleted. The computer passes malware and virus scans without issue.
I'm currently using Recuva to try to recover the available files (about 80% of the deleted files appear to be recoverable, but some critical files are not.) The recovered files are being saved to an external USB drive.
The only time I've had this problem before was corrected with chkdsk. I'm very cautious about doing anything with this drive until I have recovered all that I can manually.
It passed Spinrite with no issues. The computer is Windows 7 Home Edition 64-bit.

few folders in my external hard drive are missing. I am running a scan and hopefully it'll fix, but it takes so long to scan the hard drive as it's a 3 TB hard drive.

I was running Windows Vista 32bit on my Dell Inspiron 1545. I then decided to install Windows 7. I installed the 64bit version. Everything seemed ok apart from my CD/ROM drive. It works now and again but will suddenly disappear. I have seen people saying clean it but I dont think this is necessary as it worked a treat on Windows Vista. I tried to burn a disc in Windows Media Player but it says "connect a burner & restart the player". I have tried deleting the filters in the regedit. I have this morning re-installed Windows 7 but instead installed the 32bit version

Ok I have a Dell Inspiron 1545 and my dvd drive keeps coming and going. The drive is a TSST TS-L633B 12.7 SATA Trayload 8X DVDRW. The pc is a dual core pentium with 3gb ram. When loading a dvd the drive will show up and then shortly disappear. Sometimes it will stay longer but if i pause a dvd it will disappear again and i have to either reboot or open and close the tray to get it to recognize again. I have removed the driver from device manager and i have tried updating the driver with the latest windows 7 drivers from dell with no luck. When i try to flash the drive with the latest the driver it will be there but when opening the flashing program is disappears again. I have even gone the route of getting a replacement drive from dell and it does the same exact thing.I have gone and tried the upperfilters and lowerfilters and that did no change either. I have checked the bios and the drive shows up in the bios.

I have a Seagate external drive hooked up. I back all my data up to it. The other day I accessed it and to my shock ALL FILES were gone. Poof. We're talking thousands of files. Weird though, the folder structure/tree was still completely in tact!! Every folder is there, it's just the files that are gone. I used Recuva This and got about 60% of it back. The other 40% is gone forever I guess. Very sad as there were about 500 family images that we lost.
Anyway, I add more files to this drive about three days ago to test. Sure enough they TOO are gone now but their folders are still there! Ugh! Important to note these files are NOT going to the recycle bin for some reason. They are just being zapped from the drive somehow.
SOMETHING/SOMEONE is making my files disappear. This drive is NOT being shared on the network. I ran scan disk and no errors were found. I have run numerous anti virus and spyware removal software and only found some spam trojans. Nothing of the malicious variety (that I know of). I also ran SeaTools and the drive seems fine. I have another USB drive and it is also fine and files are NOT disappearing from it.
Here is my HJT log if it helps.
Has anyone ever heard of this before?

Problem Description: I boot up my PC, everything works fine, after an hour or so, my D (Secondary internal drive) disappears and the system has to be rebooted to find it again. Note, this happens whether or not the drive is currently being used.
Note: The drive always appears in the BIOS.
Drive: Seagate Barricuda 7200.11 750GB
Serial number: 9QK1GAKJ
Disk model: ST3750330AS
Steps I've taken to try and solve the problem: Initially I thought the drive was simply being unmounted, so i attempted to mount it again using disk management. However the drive won't appear there either, nor will it appear in system information or Seatools. A disk rescan won't reveal it either. I later, tried to use SeaTools to find out whether or not there was something physically wrong with the drive, but the drive passed all the tests. Peculiarly enough, when the D: drive disappears it also disappears in Seatools. Thirdly, I checked my power settings to make sure i hadn't had some timer for the hard drive to shut off. Fourthly, I checked the bios settings to make sure there wasn't some sort of power policy conflict there as-well. Lastly, I scanned the disk for errors with the windows (with both options to recover bad sectors and fix errors checked) and rebooted. (The problem still occurs) I will be trying to turn off the bios's plug and play settings next, and see if it will work better if i should let windows handle the device detection.

I have a hard drive I want to backup to a 64gb flash drive and then restore it to another different hard drive than where it came from. I have windows 7 and office on my laptop and I want it on my desktop pc. There isn't close to 64gb of info on my laptop so it should be fine even though the hard drive says I have 160gb. It is all free space except for those programs.

So, I have a i7 2600K system with a solid state disk as the boot drive, and an older (c2008) Samsung Spinpoint F3 500GB drive as the data drive for programs (that I deem as not worthy of the quick load times). The hard drive has given me some errors over time, and I bought a hard disk to replace it (a Hitachi 1TB). The issue I'm having is that the fact that Windows 7 puts a small (100MB) partition on the F3, and for some reason, even though I'm running Acronis 2012, it doesn't seem to be able to clone the F3 over to the Hitachi. I've also tried Drive XML, and for my 2 hour wait, I only managed to acquire a boot error. Thankfully, I've not done anything rash to destroy the data on the F3, but given the fact that I've seen corrupted files in Steam from that drive, I'm not will to trust it long term with my data. I really need to get the data onto that Hitachi, though... Anyone have any advice for upgrading the HDD in a SSD/HDD system? I don't really feel like it should be so hard, especially if I've bought Acronis True Image, but maybe they haven't designed their product to handle this scenario quite yet?

I have a HP Touchsmart IQ500. Turning my computer PC on today, all I got was a blue HP invent screen with setup, boot menu, system recovery, and system diagnosis, and I could not get past it. I entered the BIOS and figured out that the hard drive was listed as "not installed." Pretty sure that is the main problem.I tried a system restore (with the Windows 7 install disc), but I guess the computer couldn't read the hard drive enough to enter safe mode (I tried restarting and F8ing several times). I put in an external hard drive, and the BIOS read it; however, windows does not allow you to partition an OS on a hard drive.

Me and my brother built me a new computer from scratch (he did the building - i did the watching). I purchased an internal hard drive from Overclockers UK. It's a Samsung 1TB drive. I also have a 64 Solid-state drive in there as my primary hard drive that Windows was installed on and a couple of programs are installed on. My storage disk (the 1TB disk) is for all my music/films etc. Whenever I drag and drop a file into the Samsung hard-drive - it copies it rather than moves it instantly.When I had a laptop, I had 3 external hard drives and this is the way it copied files onto them.how I can get the internal drive to stop acting like an external drive?

I'm planning on buying an Asus Zenbook UX32VD soon and it comes with a standard 7200 rpm drive instead of an SSD. So because of that i want to upgrade it to an SSD drive.But I also want to have the same windows thats installed moved over to the new drive. The drives i've looked at all have data migration tools and one comes with norton ghost but i've never had to do something like this before where i didn't have an optical drive and a windows disk for a reinstall so i'm looking for some help here before i order everything and then do something stupid.i don't mind if i have to lose whatever settings and data i might have setup already, but i just want to make sure i have the same windows and the additions it comes with moved over to the new SSD drive.

I have tried numerous times on my PC to install Windows 7 onto my Sata Drive to no avail. Yet as soon as I plug in my IDE HD it installs fine.I have unplugged all external peripherals USB and internal Card Reader. Set my Bios ok as it sees both the Hard Drive and DVD fine (Both in the bios and during selection of hard drive during windows 7 installation). Yet when I come to install it, it craps out at a random percentage saying cannot read from source or worse yet it crawls so slow through the percentages (I really don't think Windows 7 should take 6 hours to get to 15%!!) Yet both the hard drive and dvd are fine and the disc works great on my other PC without the sata drive in.
My motherboard is a Biostar G31-M7 TE with latest bios now what is odd is that I recently updated the BIOS to the latest one so does my problem come from here or was it always going to be a problem on this board? Also when I do have Windows 7 installed on the IDE drive when I plug in ther sata drive inside the whole system goes belly up (from freezes when transferring large files to just not seeing the drive)

I have an Alienware M14x R1 with a SSD - Crucial M4 in the main spot and the stock HD in the optical drive. I have never had any issues with any of this stuff before this clean install - and I have done clean installs previously. I also used Parted Magic to Secure Erase my SSD and HD before install.I am experiencing some pretty frustrating problems:
1. I have NO INTERNET CONNECTION (everyone keeps telling me to install drivers...how can I do this without internet connection??)
2. Windows is not recognizing my second hard drive in the optical drive even though it did when I was installing and showed it at the section where you can add new partitions etc
3. My display adpater is not working as I have a 1600x900 screen and I can only go up to 1024x768...

make a dualboot comp by adding windows XP to a new partition. I created the new partition with 20gb. (From the 500 of my actual harddrive)But before I actually installed on that, I got distracted with a second harddrive that my dad got(for no reason). It had a full copy of Windows XP backed up on it from another computer, so I figured I would just use that for the dualboot. I plugged it in (wired the same way as my old harddrive, but different data slot), restarted, checked the harddrive in explorer - all the data was there / reading correctly / etc, and I used 'easyBCD' to add the new harddrive to the boot list.(Which, of course, crashes if I try to start it. I just wanted to see what it would do). For a reason I can't remember, I unplugged the second harddrive for a bit, started the computer on accident (I don't know if anything loaded before I shut it off), and then when I plugged it back in.Windows 7 would not launch. It goes to a DOS-like window, except it's just a flashing _ and it never does anything even after a few minutes. XP didn't work still.. so I decided to reinstall XP (as I couldn't tell which harddrive was which on the list, I unplugged the main harddrive while installing onto the new).. and when I did this.. it formatted and installed fully... then restarted.. then restarted.. and restarted.. and just kept restarting, never showing any thing past the manufacturer logo/BIOS load-button-message-thing. So, I then try to use my 3-disk Windows7Recovery disk(burned myself with a program apparently included by the manufacturer.) It installed fully, appearing to work.. but when I launched it, it said "Invalid Partition Table" and wouldn't boot past that. When I insert my driver installer disk, it gives me a basic DOS window thing. dir A: shows the files in the disk. dir B: for some reason shows the same. C: says "Error reading from drive C: DOS area: general failure". All other letter:'s just say "invalid drive". (I'm doing this with both harddrives in.) I attempted connecting the harddrives to an old computer, but it gave an error for both. (It detected the harddrives, but said it had an error reading from it. Windows Explorer asked me to format it... {i'm willing to format one of the drives if anybody thinks it will help, but the old harddrive has data I'd prefer not to lose.} ) Looking on google, I saw several problems that all have similar problems (less overdescripptive than I am though) but none of the fixes suggested worked for me. Also - as I have two different with different errors, I only need to make one of them work.)Also - my other available computer has a CD burner / floppy drive if either are required. I also have several USB's. The computer can boot from USB's and CD's (tested), and I could easily take the floppy thingy and connect it to the computer.also - this computer is probably still under warranty unless unscrewing the hard drive voids it. .. does that count as modification of the computer?

I recently installed windows 7 home premium 64 bit, previous OS was Vista home premium 32 bit. My desktop is an HP pavilion d4650y. I have the OS loaded on my main HD which is a SATA.
HD & DVD drive worked perfectly before on vista. I tested both devices on another pc with XP and they work fine. I've triple checked the connections but still the devices are not recognized by Windows 7. I've also tried renaming the HD & changing the drive letter, but still no luck.
Both drives are connected to a PCI E card, and are set to cable select, on separate cables. In the BIOS both drives show up. In disk management they do not show up at all.
My HD is a western digital 250 gb EIDE, and the DVD drive is a IDE Pioneer DVD burner (secondary disc drive).

I have a USB external hard drive that I keep all my documents etc on (had it for years)I upgraded from Vista Home to & Home Premium then had to upgrade recently to Professional to run my Sage. Through all these upgrades my ext. drive ran fine. Occasionally the drvie letter would change if I had something else plugged into the USB, this was always easily corected in disk management by changing the drive path.The connection on the case packed up so I had to get the drive put into a new case, now when I plug it in the drive is assigned G instead of F, I tried to change the drive letter allocation in Disk Management but it won't let me as the program still thinks I have a second ext. hard drive which is labelled F. I suspect this has happened because when the usb connection broke the drive was disconnected suddenly instead of a proper eject.How do I get Disk Management to remove the inactive drive - i can't find any obvious way - eject, delete etc are all missing when I click on tools or tasks.

I installed Ubuntu on my computer a few months ago and created another partition for it on my 1TB hard drive. I didn't really care for Ubuntu so I decided to delete the partition it was on. That might have been a mistake. Well, now there's 87.68GB of free space on my hard disk that I can't use and I don't know how to add it back to my c: partition.
There was another post about this a couple years ago, but I don't understand the instructions and am not actually sure if it worked. Can someone explain how to do this, please? I'm not completely computer illiterate, but I'm not familiar with partitioning disks. It was just the one time with Ubuntu.

I've been noticing after re-installing Win 7 that I get random floppy drive seeks and the hard drive light flashes like crazy and then everything is fine again.I have Clamwin AV,Spyware Blaster and Spybot S&D installed,but that's it,no Windows Defender or Essentials AV.Any ideas what causes this? It's a minor annoyance,but I just want to make sure it's not damaging anything.Also would Readyboost help me? I've got 2 gigs dual channel PC3200 ram(or I could go with 2.5 gig single channel PC2700)and a P4 at 3 gig until I can afford to upgrade my comp.This is my first post in quite awhile so I hope this is in the right place
