It looks like you are using a wide scsi disk behind a wide-to-narrow
converter. Thus, I am supposing this disk is not the disk which was in
the machine when you received it.

Have you tried with a regular narrow disk? Does it work better? The PROM
might not be able to talk to your drive correctly.

You might also want to check if your disk is jumpered to ID #2 or to ID
#10 (which is more common for a wide drive and, through a wide-to-narrow
converter, will appear as ID #2).
