Are you sure hardware is OK i.e. no clashing SCSI IDs, chain terminated at
both ends etc. Does the Adaptec BIOS see the drive OK ? If you go to the
Adaptec BIOS (probably ctrl-A at the BIOS banner, then select your
controller from the list, given that you have two) can you run verify on the
drive ? Have you tried the drive on the other controller (or the other
channel - I'm not sure if the messages you enclosed showed two cards or a
dual channel card, though I think two cards).
