You may want to try putting the drive on the same cable as it previously was (master or slave shouldn't matter). I have had this problem with a drive before a year or so back, and I was told it had something to do with the controller chip for the primary IDE not being the same as the secondary IDE (one was UDMA 33 and the other was 66... or somesuch on the particular motherboard) and thus the drive geometry was getting differently detected.
