^^^^^^^^^^^^^^^
Does your Adaptec controller have a BIOS configuration screen? If
so, see what the sync rate is. It is possible that the new drive
has negotiated with a sync-rate it can't possibly handle. Manually
set it to the next lower and try again.
Also, make sure the ends (both ends) of your SCSI cable are terminated.
The auto-term in the Adaptec controllers I have used is not sufficient
for fast drives. The fact that the BIOS can see a drive means nothing!
The drive name, etc., is handled via a slow-speed inquiry command.
You can see most drives when they are connected without any termination,
even with very long (too long) cables.
