Hello everyone! Here goes my first post ever.
I'm having trouble with my HDD's. I've got two hard drives installed in my computer, one parallel ATA (Maxtor 80 GB) and the other serial ATA (Hitachi 160 GB). The PATA one has three primary partitions, two of which hold Windows XP and 2000 respectively (it's a dual-boot system). The SATA disk has a single primary partition, holding only random files, as does the third partition on the PATA disk.
The problem is, when I log into Win 2000 and start browsing the files on the SATA disk, it reports a corrupted files error and can't read the contents. After that, when I boot Win XP, it automatically runs chkdsk before the Logon screen, verifying indexes, repairing corrupt files etc. I originally formatted and filled the SATA disk with files under Win XP. All files on all PATA disk partitions can be accessed by both OS's without problems.
After almost losing all the data on the SATA disk once, I disabled it in Win 2k. Is there a way to fix this and have all disks running on both OS's?
Thanks for your help!

Any chance you are running SP3 and set the disk up under XP using a GUID partition table rather than MBR Partition table?

I am running SP3, but I formatted the disk before installing it (i.e. under SP2). I've read GUID is not common on Windows, so I really do believe it's MBR. But is there a way to check this?
I also forgot to mention, I formatted the SATA disk using PartitionMagic's wizard, but I've also done that on the other disk, the one I don't have problems with. Should I re-format the disk using Windows' formatting utility?
Many thanks, sorry for replying so late.

Yeah, no reason to use any third party tools - if the OS can do it, I always use the OS....
