    Hard Disk Issue


    Hello,

    I have a problem with my data hard drive (ST3000DM001-1CH166 ATA (3 TB)), which suddenly shrunk to 128GB.

    I went to Disk Management and it shows one partition of 128 GB unallocated. I haven't formatted or anything as I wouldn't like to lose the data I have on it, which amounts to over 1TB. I went to BIOS and, to my surprise, it no longer reads the disk as a 3TB drive but as a 128GB one only!! I successfully updated the BIOS to its latest version and still... no luck...

    Then I read somewhere SeaTools (DOS version) might do the trick so I downloaded and burnt it to a CD, then I ran the program and it said there was an error in the partition of the hard disk in question.

    I truly don't know what to do... I'm thinking of taking the computer to the shop so a professional can look into it, but if anyone comes up with ideas, I would really appreciate it!

    System Restore:
    1. Go here --C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\System Tools\ and run the program cleanmgr.exe
    2. Now click "Files from all users on this pc"
    3. Click OK
    4. When the windows opens up click the tab "more options"
    5. Then click "System restore and shadow copies" tab "clean up" Click delete
    6. Then OK
    7. Then Delete
    8. Check your hard drive space I you will have gained a lot of gigabytes back.
    9. Done!

    Warning!

    1. Dont do this too often because if something goes wrong with the pc you wont have anything to fall back on
    2. Don't disable system restore, its there to protect the system, can you imagine you if did a windows update and updated the graphics driver and it disable your display? You wont be able to roll back because there would be no restore point.

    Thanks for your suggestion...

    I did forget to mention that, even though my shrunk hard disk shows in Disk Management, it doesn't in "My PC" so when I run cleanmgr, it does not give me the option to click on the hard disk I'm having issues with. Besides, I don't think it's a Windows problem as BIOS only reads 128GB out of a 3TB capacity. The paradox is the disk had been working fine for over a year, and I haven't touched anything in the BIOS nor have I removed the hard drive or anything for that matter... It just suddenly shrunk, out of the blue...

    There IS some slack when you format NTFS - a 320 GB hard drive will have about 298gb of usable space.

    a 1TB Drive? You get 930 gb of space - On NTFS.

    a 2T drive, you get 1.81 T.

    So - A LITTLE slack is totally normal, but if you are missing half of the drive, well... Then check for previous installs of Linux, which when deleted leaves a partition unreadable and undetectable by the Windows 7-8-8.1 Disk Manager.

    If there's a problem in the BIOS nothing in windows can fix it, check MB manual to see if there's a setting for disks over 2.2 GB.

    But it had been working fine for over a year.:. And I didn't modify the BIOS or anything... Can it be a BIOS problem? Should I try my hard drive on another computer? If I were to configure the BIOS again, is there any parameters I should check to restore the full 3TB?

    It's good idea to try on another computer but keep in mind that not all of them support disks larger than 2.2 TB. You have UEFI and Legacy BIOS there, try booting in Legacy mode.

    How can ai do that? I mean... Can you tell me the steps to take once I'm on BIOS?

    I've also found this:

    Restoring Factory Hard Drive Capacity Official Atola Technology Blog

    May that come in handy?

    Manual for your MB is here: GIGABYTE - Motherboard - Socket 1155 - GA-H61M-D2H-USB3 (rev. 1.0) as I don't have same MB I can not help you that way.
