XP Pro won't read 80Gb drive formatted in 2000

[syf3r]

I've got an 80Gb drive in a pull-out bay, that was formatted as in 2000. When I put the drive in my XP Pro machine, the BIOS reads it as the proper size on bootup, but XP doesn't mount the drive. It does, however, show a drive letter for it. In Disk Management, XP shows the drive as a 7Gb drive, healthy, but inactive. Not sure what the problem might be... anyone know what I might be overlooking?

fat 32 or ntfs?

The drive was formatted as NTFS under 2000. I just tried putting it back in the 2000 machine and it reads just fine, so no damage was done to it when I put it in the XP machine, but the XP machine won't read it.

Okay, I just tried a 120Gb drive in another pullout bay, and it reads just fine. I have access to all the files on it. The 120Gb is also NTFS, but I can't remember on what machine I formatted it, it's been around a while. My suspicion is that the 80Gb drive was formatted on a machine on which 48-bit LBA wasn't set up properly. Since the drive is only 80Gb I never noticed a problem on the 2000 machines I had. (The XP machine that has a problem reading it is my first XP machine so I'm still getting used to it).

I also suspect that the drives I format on the XP machine might not read on my 2000 machine.

Am I right that a drive won't be readable in a 48-bit LBA environ if it was formatted in an earlier LBA? So basically I need to reformat my drives for 48-bit, or is the problem I'm experiencing separate from that?

Are you sure the jumpers are set correctly for the XP machine?

The jumpers are set to cable select. Since there are two bays on that machine, all 5 of my pullout drives are set to cable select so I don't have to worry about placement.
As I said, I just found a 120Gb drive that does work, and I also found a 60 that doesn't. I'm wondering if the two that don't work (60 and 80) were formatted under win2000 service pack 2. I do remember that I didn't move to service pack 3 or 4 for a long time. If this is the case, would being formatted under win2000 SP2 (48-bit LBA wasn't available until SP3) be a possible cause?

Actually, the 60Gb drive *does* load, and I have access to it. However, when I boot the machine with the 60Gb in it, Windows reads the 60Gb and gives it a drive letter, but also gives another drive letter that has no access. Disk Manager shows the drive as one partition, and doesn't show any hidden or other-OS partition at all.
I'm going to move all the data off the 60Gb onto the 160, and then reformat the 60 in XP, copy a few files to it and try it in my 2000 box. I think the fact that they were originally formatted under win2000 SP2 might be the cause.

It's acting weirdly enough that, if it were my drive and I decided to reformat it, I would go ahead and low-level it. Link to low-level utils, FYI --- http://www.ariolic.com/actives.../low-level-format.html
