A device attached to the system is not functioning

I was copying a large folder from an external drive to my D-Drive (120 gig) when I received an error message that the disk was full.  I stopped the proceedure and verified that there was plenty of room left on the D-Drive.

On all subesequant boot ups, when trying to access the D-Drive, I receive an error message:  A device attached to the system is not functioning.

Western Digital Data Lifeguard Tools knows the disk is there, but wants to reformat it.

I ran an FDISK (option 4 view) on the drive and the system is listed as unknown.  (C-Drive says FAT32)

Hard drive crash?

      Is it the new installed hard disk to your PC? I mean that have you ever use D drive successfully before?
    Most of the time, the motherboard for PII 333 doesn't support the disk more than 84GB. So you might want to check your PC's manual
    for it.

    I had been using it successfully for about two months and the computer knew that the D-drive was a 120 gig there.  I was transferring about 10-gig if files when it choked.  Is it possible that things went bad when I exceeded 84GB?

    The C-Drive is an 80GB drive and it is functioning ok.

      I've multiple old P2 or P3 machines (Dell) whose CPU are below 550MHz.
    Those machines don't recognize the HD more than 64GB, I mean that it shows up on as D drive
    in Windows but behaves strange.

       Besides, I can find the right information from HP's website (#X?$#!!) for your model,
    so you might need to check your manual.

       Or you can put your 120GB HD to other PC (or friend's) to test out.

    I've ordered an external hard drive enclosure and will try the drive on a laptop to see if it fires up under Windows 2000.

    I'll let you know later this week if that works.

    External Hard Drive solution didn't work.  Neither did Convair data recovery software.  (It saw all of the files, but they were corrupt.)  I ultimately gave up, reformatted the drive and it is now a working drive.

    You were right about the Pentium II not liking a HD over 64GB.  I was copying material to the 80GB C-drive and it corrupted as well.  Fortunately, the Convair software was able to reclaim those files.

    I'm hitting the accept button and awarding the points.  Thanks for trying to help, and the heads up about the 64GB limitations.
