My reaction would be to remove the new drive and get the system 
working as it was. Once that is done then I would assign a new SCSI ID to the 
new drive and put it between the the two old drives and make sure the new one
is NOT terminated.  Termination should be handled by the earlier drives.

Is there anything flaky about Linux on the Alpha?
