Jerry,
This may be obvious, but are you sure you don't have both drives set
for the same scsi ID? It "sounds" like the two drives are in contention on the
buss, which is often caused if they have the same ID. Otherwise, the problem
could be termination. If each drive is set to a different scsi ID, then be
sure that the LAST drive on the chain is terminated, but the first one is not.
If you don't know what I mean by termination, look just behind the 50 pin
connector on the drive and you should find two or three resistor packs side by
side in sockets. To unterminate a drive carefully remove the resistor packs
(but put them away somewhere in case you ever need them).
