Hard Drive Not Detected By BIOS Or Disk Management?
Aug 27, 2011
I'm currently using a Windows 7 PC built by a friend of mine, but starting yesterday, its been acting up. The problem is there used to be two hard drives I can access, Drive B and Drive C. When I boot up the computer, BIOS only detects Drive C (if I'm not mistaken), and Disk Managements as well. I realized this when all the programs whose targets are on that drive are all broken on the desktop.So Drive B doesn't show up anywhere at all.

My hard drive, a WD Scorpio 200GB, is not being detected in bios. AHCI mode is enabled. When I go into the Advanced BIOS Features, all the master and slave configs are none; however, my SSD is recognized as I am on my computer right now using it. I tried every SATA Port, EVEN THE SATA PORT MY SSD IS INSTALLED ON, and it doesn't work; I tried 2 different cables and still no recognition; I tried 4 different hard drives and still no recognition, so it is not a problem with my motherboard, hard drives, or cables. What should I do? I have been trying to figure this out for 4 hours.

Lots of BSOD, lock ups, hard drive not being detected by bios, is it failing? Let me start by saying my PC is custom built, most parts are only a year old. The oldest parts are the harddrive (about 5 years) and the soundcard (about 7 years). I have never had major problems until now (a year after building it).
It all started with a blue screen.
KERNEL_DATA_INPAGE_ERROR
Reboot windows and it seems to start up fine, gets to the desktop and locks up.
Reboot windows and I get another blue screen.
BAD_SYSTEM_CONFIG_INFO
I try to start windows from the last good configuration. Error. Registry file failure. Cannot load hive file. I try booting from the windows cd and running a chkdsk. Hard drive starts making a buzzing sound. It gets to step 3 of 5 and stops. Failed to transfer logged messages. Status 50. Now the bios rarely even "sees" the drive. When I can get it to boot and see it, any attempt at diagnostics and repairs produces errors, locks up, or fails.
Is this a bad hard drive? I would hate to spend the money on a new one only to find it is a bad mobo or virus. How can I diagnose this? If it is a bad drive I would like to save what juice is left in it and try to recover a few files before it dies. Most of the important data has been backed up but I would like to try and get a few game save files if I can. But its not a disaster if the drive data is not recoverable.

There was originally just one HDD and I wanted all my "Media" to be in one partition and then Programme Files etc. in another (being C). This was just so that I could copy the entire 'Drive' I had created making moving videos and photos around easier.So I used the built in disk partition manager and created some unallocated space, then called that space Drive (A) - But now that (A) drive is full and I want to add an additional 40Gb to it from the original C, but I the "Extend Volume" option is greyed out on the (A) drive even with the 40Gb as Unallocated.

My friend's laptop (Acer Aspire One 722 - Windows 7 x64) has been shut down after opening an email and Windows never started up again. When you attempt to start up the windows, it stays the black screen and says "No bootable Device Found"! I inserted Windows Live Disk and loaded it (Windows XP Mini - Golden Edition). When I went to "My Computer", it did not show any local drive. I went to "Disk Management" and in there, there was also no unallocated or allocated space. I even removed the HDD and plugged it back in. No thing happened. Then I removed the RAM card and inserted it back. Again, nothing happened! By the way, HDD had movements when laptop was on (I had removed the beneath panel).I inserted Windows 7 Disk to install a fresh Windows 7. But when you get to the part where it asks you to choose the partition to install the operating Sustem, it shows one unallocated drive with 0 (Zero) capacity! The options to Delete and format are disable. Only the option "New" is active and it gives you (0) bite to partition!

I use a lot of different usb hard drives in my shop. I have two basic enclosures, a generic one that uses pata drives on a usb 2.0 cable and an Apricon USB SATA 2.0 adapter.Suddenly when I plug in a new drive device manager does see the drive and installs it in device manager. I can see the drive in Disk Management but it has no drive letter assigned, and therefore doesn't show up in Computer. I can easily just assign a letter in Disk Management and the drive immediately becomes usable. However, I would like to get Windows 7 to resume automatically assigning a drive letter.
I have tried a program called USB DriveCleanup. What it appears to have done is remove all installations of prior USB drives and when I plug in a drive that has been in the machine previously it then goes thru the install again. Yet still no drive letter. I think the program is doing what would manually be done by going into safe mode and cleaning out all the entries that build up there that don't appear in normal mode, then removes them. Basically it seems like a shortcut to manually doing it.
I also tried a registry fix that essentially asked me to delete the upper and lower filters. This seems similiar to fix for CD/DVD drives that no longer appear in Computer. This fix also didn't work.I tried removing and reinstalling the chipset drivers. Still no go.Running Windows 7 Pro SP1, H55 chipset.

I have a 1 TB Western Digital Caviar Black hard disk. While installing Windows 7, a screen for hard disk partition was asked. I created 4 drives: 200 GB, 200 GB, 200 GB and 400 GB. And then the windows 7 got installed. But now when I log into my PC, I can only see first 3 200 GB drives. Where did my 400 GB drive go? What mistake did I do and how can I recover it back?

My C: drive has been displaying a size of around 60 gb with 40 free even though it's a 300 gb drive. I thought the issue would resolve with a clean install, so I did that. Now I have a fresh install and i need to reinstall everything, but the problem isn't fixed. Below are some screen shots of the drive size:Disk Management, showing my C: Drive's full size ^Any suggestions of how I can reclaim this space?? I've tried a few things already to no avail. If you need any more information about my computer to help, let me know. This is pretty annoying, 'cause I want to use that extra space to install Ubuntu.Oh, I just rememberedWhen I look at the drive in Paragon Partition Manager, it shows the full Drive size, but says that the space that is missing from Windows is in use...

My backup software's profile database is expecting to backup to H:, which was the drive letter for my external backup drive back in XP. This drive comes up in Windows 7 as K, because Windows 7 has given my four usb card reader drives the letters F,G,H,I.
Disk Management will not show these four card reader drives unless media is inserted (connected vs. disconnected). I have changed the letters for F,G,I to T,U,W, but only because I have those types of cards (SD, CF, MS)...I do not have an XD or SmartMedia card for the one dang drive I really need to change.
What are my options, other than buying the cheapest SM card I can find to make the drive visible for this task? The SmartSyncPro database has many profiles, so remapping all those to point to K would be a major hassle.

I needed to copy files between two PCs and didn't have a USB big enough so I took the HDD out of my Dell Vista laptop and used it as an external drive to transfer the files I needed moving. When I connected it up to the destination PC running windows 7, the drive couldn't be seen in explorer. I had to bring the drive online in Disk Management in order to be able to explore the drive and take the files I needed off of it. All was OK until I put the drive back in the Vista laptop and then found that the drive wouldn't boot. All I get is a blinking cursor after the initial Dell logo screen. like as if the BIOS can't load the drive or something.Can someone please tell me what bringing a drive online in Disk Management does to the MBR of that drive?

In my Sister's laptop, running Windows 7 Ultimate x86, all of a sudden, while she was working on the computer, the "E drive" went missing which was a partition on the hard disk (I don't remember if it was a logical or primary partition). She tried restarting the system but to no avail. So, I told her to open the "Disk management" tool in Windows 7 to see if the partition is visible in there. I did this because sometimes, in my computer, my expansion drive wouldn't show but it would be visible in the disk management tool and all I had to do was to re-assign it a drive letter. But, in this case, it wasn't visible over there.
So, now I told her to download "Mini-Tool Partition manager Home edition" and install it on her laptop. On running it, it wouldn't show the partition either. It would just show "C:", "D", "System Reserved" and unallocated space. However, when I added up the size displayed by C:, D:, System Reserved and Unallocated, it doesn't add up to the actual hard disk size. It means the partition is somewhere there but not visible. Is it possible that the partition would show up correctly if the laptop is booted into the bootable image of Mini-Tool Partition Manager?

How to force format a flash drive? I have an 8gb flash drive and I plugged it in to a speaker that plays mp3 songs. But after unplugged it, my flash drive prompts "Please insert disk" and 0mb in my computer. I tried to view it with disk management and I saw its partition type was RAW.

I have an external HDD that works on any other machine I test it on, except mine. It was working and for some reason I recently needed to use it and it didn't work. It appears in device manager but not in disk management. A drive letter might not be assigned to it, I can't see it in disk management to assign a drive letter to it.

I just noticed that in Device Manager my printer is showing in the disk drive section as a USB device, and in the printer section it is also listed, where it shows my printer as a (DOT4PRINT), and lists a printer as: Printer IEEE 1284.4 compatible.

so I got a new asus P8z68-V pro motherboard. Im re-using my current 750gb SATA drive. I plugged it into the sata port, and start the computer. When it starts it says "no hard drive is detected!" I go into the bios, and on the bottom it has a disk drive, and a SATA drive. It recognizes that the sata drive is there, but when i go to start up it says no hard drive is detected. I have tried a few different sata ports and it is the exact same thing.

I've got an issue during post installation. One of my hard drive is never given a drive letter, but it does show up as a possible install drive during setup.
I always have to go into Drive Management and assign that drive a letter (and moving my DVD drive down a letter to keep the letters in order).
Under Drive Management the drive has the Properties (System, Active, Primary Partition), so I'm wondering if that is the issue.
Is there a way to change Drive Properties (if that is the case)?

having an issue with a brand new HD I bought. Right now Windows 7 will not detect the HD as a drive.It shows up in the BIOS correctly, but not in My Computer. It is in a Frankenstein setup: SATA connection into the SATA port on the MB (it is enabled and showing), with power from an external HD enclosure.I don't think that would affect it though, as it is just drawing power from a different PS.i did some digging and found it in the System Information under 'discs' instead of 'drives' like my original HD.[URL]...
