    Which file system did You choose when the drive was formated?

    Windows XP can not format a partition, larger than 32 GB to FAT32!

    Right-click the "My computer" icon > Manage > Disk management > what does it display? 32 GB FAT32 and 10 GB unallocated space?

    Only thing I can think of.

    FDISK should format the full 40 GB ...... :confused: ...... since You don't mention it, I suppose there was no unallocated (free) space in Disk Management?

    Did You change the jumpering on the drive? It's common for drives to have a jumper position to limit the size to 32 GB.

    Disk recognition is a BIOS function. Look in the BIOS for the size. Would check mobo mfgr. for possible update that sees large disks, and download and flash if available. But take care to get the exact one for your board!

    Mike,
    as I understand the situation, the hardware is the same, only a new operating system. BIOS recognized the full size before the attempt to install XP. I may be wrong, though!

    hi,

    I don't think it's the bios because it was detecting the full 40Gb.
    Could be the jumper.
    but if i reconfig the jumper will it detect the full 40Gb or do i have to format the drive.

    I think you can get it back.

    I am gonna gamble here. Or take a wild guess. Your call.

    I would be willing to bet that if you run FDISK it will show 30gig as the C: drive and the rest un-allocated ( or what ever it says )

    That could be set up as the D: drive.

    If this is the case I myself would change that to a 10gig C: and 30gig D:

    As I said. This may be a WILD guess because I have not set up and formated a new drive since WAY BACK in the days of Win95/98FE. And I think it was a 20 or 30gig ? at that time. I am now on an 80gig running XP Pro.

    Yes, if it is the jumpering that is the cause but the recovered space will show up as unpartitioned space.

    You can merge the 10 GB to the 30 GB using a third party program like Partition Magic but not using neither FDISK nor any XP utility. The latter two can only partition and format the 10 GB separately.

    I quote BillyBob:

    Changing the drive letter for the system partition (from C to D) would probably lead to problems (a messed up boot.ini). The system partition would still be the larger one but with a different name (with no reference in boot.ini).

    Reinstalling XP to the recovered 10 GB partition would mean that its position is at the rear of the harddisk which is the slowest part.

    If You get the BIOS to recognize the full 40 GB, I would recommend taking it from square one, a fresh installation involving the removal of the current C: and the creation of a new C: which uses all space (40 GB).

    Remove, create and format during installation (from the XP install CD). Since the size is more than 32 GB, the only option will be to format NTFS (full format).

    I hear you. But not if you were to wipe it out and start again as you suggest in a later suggestion.

    Which I was actually thinking of.

    But again I may be grasping at straws beacuse it has been so long. And the newer stuff may well be quite different.

    I would like to see the machine booted to a 98 SUD. And see what that says.

    And if it sees the full 40gig, run FDISK and Format from there.

    An excelent mobo! But you need the BIOS upgrade from ABIT, from this page.
    http://www.abit-usa.com/products/mb/bios.php?categories=1&model=89

    Actually, the BIOS MAY HAVE CHANGED for some reason, for example, an old battery. and flashing it again with the current version (from Abit) may correct it. I'd change to a new battery first, too.

    BillyBob,

    DOS just reports what the BIOS tells it about hardware, and so does windows.

    Other than using the full 40gig in one partiton I suggest starting over using FDISK after a 98 SUD Boot. ( assumming you have one )

    If you do not redo the whole thing there is a possibility of it not working properly.

    I would also leave any 3RD party software out of the process. I have used 3rd party software in the past and wound up with nothing but problems.
