    6th link down is

  3. I threw a 160 GB drive in my Windows 2000 (SP4) box the other day
    which recognised it as above, I searched and found a registry key had
    to be added to Windows manually for it to 'see' drives using 48-bit
    LBA. The key was

    Create a DWORD key 'EnableBigLba' and set it to 1 (0x1)
    Then reboot.

    It worked for me.

    Google often gives too many irrelevant links.
    Typing in hardware (ie hard drive) & review for example will give
    pages & pages links to ad's & online retailers.

    Brilliant! Thanks for that Kristofer, now my trusty old P500 file server can
    see all of its new 200GB HDD. I assumed it was a BIOS limitation that I was
    stuck with.

    And thanks to John for posting here instead of using Google, I wouldn't have
    discovered this otherwise ;-)

    Your BIOS doesn't support LBA48, which is needed to recognise any drive
    over 128GiB.

    Even with that the software needs to support it too, which
    means, I think, SP2 on XP. Even then he might need a large
    disk patch from the manufacturer. This article talks about
    the situation.

    SP1 or greater for XP.

    Actually some drivers will access the drive directly without going through
    the BIOS. I suspect this is what happened on my Windows 2000 machine. The
    BIOS sees the 200GB drive as 6GB, but after making the registry modification
    that Kristofer mentioned Windows sees the whole drive.

    I think Partition Magic uses the BIOS though.
