So you just added another scsi harddrive to your chain and the transfers get corrupt ?? Strange. I do remember having had the same problem with my ex A500+ with 68020i turboboard. On the back of the manual was written that I had to decrease the MaxTransfer in HDtoolbox. Maybe your harddrive is too fast and its speed needs to be decreased a bit ... don't throw it away yet, it doesn't mean that there's something wrong with the hd ...
