Hard drive not showing up in Windows

Hi all, really hope someone out there can help me!

I have a SATA hard drive which shows up in BIOS, but not in 'Computer Management' or 'Device Manager'. Does anyone know why this could be?

Surely if it was dead, it would not be in BIOS, but Windows doesn't seem to see it anywhere..

Thanks,

Mark

    I hope this answers your question.


    Windows 7 hides empty drives (both fixed, and removable drives) by default, but many people don't realize this. If you could swear you had a freshly formatted drive just hooked up to the computer, but can't seem to find it, click on Organize, Folder and Search options, select the View tab, and uncheck the Hide empty drives in the Computer folder box.

    If the drive is not yet formatted, make sure you run through the steps above (so you aren't further confused in a minute), and then type diskmgmt.msc into the Start Menu search bar. Here you should see all drives connected to your computer. Format as necessary and then they will appear in the Computer folder.

  2. I just put a new 500 GB drive in my system and it shows up under "Disk Management" from there you just format and it's done!!!!
    Are you running win7 or xp/vista?
  3. Sorry, should have said it is a hard drive which I have been using in an external case (actually, it came in a My Book).
    But it disappeared one day and so to try and get the data out, i took it from the case and plugged it in directly, so it is formatted and full and was working for a couple of years.. but then suddenly disappeared and now is no longer accessible.
    While most recovery tools need to see the drive, Windows seems to now know it is there. However, it is in BIOS, so perhaps there is something else which can find it, or a way to force Windows to find it.
    But as I said above, it is not in Device Manager either.
    Thanks for your replies!
  4. As it "disappeared one day", I would guess that there is some fault with it. This would explain why Windows can't see it.

    One possibility would be to boot from a Linux live CD to see if that can see the drive.
  5. The thing is that would BIOS see it if it is broken? I did try to boot into an Ubuntu CD, on my laptop, but am unable to try on a desktop at the moment.. I am not really familiar with linux so wasn't sure where to look to be honest, but it wasn't automatically found when connected by USB.

    If it wasn't damaged (either the hard drive itself or the partition) then it should show automatically on most Linux setups. Do you know anyone else with a Windows computer that you could try it on? How about another hard drive that you can try in the enclosure?

    I'm afraid there are situations where a drive will show in the BIOS but is so badly damaged that it is unusable in an OS.
  7. I see. I was hoping that the fact BIOS can see it might mean it isn't completely dead. But it is looking that way.. Strange because it was just sitting there, working perfectly..

    I don't have another drive at the moment to try, but perhaps will try that when I get the chance.

    Well thanks a lot for all the feedback!

    Excellent answer. *bow*
  10. i have a similar problem. sometimes the HDD shows up in the BIOS and sometimes it doesnt. i havent been able to fully load and OS onto it yet and i assume its formatted because sometimes it shows up and i try loading an OS onto it but it seems to disappear after a while. ive plugged it in and out on different SATA ports on the mobo and it varies which one allows the HDD to show up in the BIOS. do i just have dodgy SATA serial and power cables?

    Here are some solutions to try:

    Right click my computer/ manage/ storage/ disk management allocate and assign drive letter.

    Another very nice guide to try step by step:

    And finally --

    If nothing else works..

    Take drive out -- put in another working computer and format with that computer. Now put drive back into your computer,.. and often that works.

  16. Yes, I knew there was away to unhide a HDD, but for the life of me I forgot, so thanks for reminding me :) an it worked

    Yes, this solved it for me.

    For some reason, Pata's solution (running diskmgmt.msc from the start menu) did not show Disk 1, my second disk. But when I ran Disk Management from Manage - Storage etc. it showed up, and I could assign it a letter and format it. Weird. Thanks!
  18. This helped me solve my problem as well.

    The only extra work I had to do was format the drive using command prompt.

    Here are the commands I used to format:

    Quote:
    Diskpart

    list disk

    Select Disk N (N is the number of the drive you want to format)

    Clean

    Create Partition Primary

    Assign (You get option to format now - I choose NFTS and 4096bytes as I will be putting large files on the drive)

    Exit


    Your drive will now be formatted.
