First time user here. I just want to thank you in advance.


I have a 200 GB western digital hard drive. When I place it in to my DELL 260 Optiplex it shows as a 128 GB. I am running Windows 2k Server SP4. The BIOS is showing at 200GB only the OS is showing 128 GB.

Any suggestions.

    To enable 48-bit LBA large-disk support in the registry:
    1. Start Registry Editor (Regedt32.exe).
    2. Locate and then click the following key in the registry:
    3. On the Edit menu, click Add Value, and then add the following registry value:
           Value name: EnableBigLba
           Data type: REG_DWORD
           Value data: 0x1
    4. Quit Registry Editor.

    I am sure what callandor suggested will work, however if it does not just as another thing to try out :

    Get partition magic and see if parition magic displays the un allocated space :)

    Then you can use parition magic to allocate it :)

    If that does not work, then isnt there an update for windows 2000 that will enable or allow you to use larger hard drives.
