I think you did something wrong in formatting and/or installing if it happened to two different drives one after the other, this is what I would do, download your hard drives installation utilities, and run it to check the drives, it may just be a formatting problem (you can only format 4gig under NTFS for setup to work, then you can format the rest in NTFS after install), clear up everything, I would use the hd installation utility to partition and format (takes approx 4 min on a 60gig drive) then start win2000 installation. If you got this far and you still get corruption, start over and install under fat32 then convert the drive to NTFS after installation.
PS. unless you need file protection/security/compression, why not go with fat32, faster, easier, etc. lots of other good reasons.
