Thanks all. After my original message - here's what I found

There are 2 possible causes for my trouble!

1/ The drive was on SCSI ID 4. After I changed it to ID 1 (advice from the
Sun vendor), the drive was recognised. This is the only change I made
(apart from 2 below) - although I haven't since re-tested the drive back on
ID 4 - it would appear that I sent the drive back to the vendor (losing 2
months!) for this reason alone. Perhaps Sun would like to write this in
huge letters all over their machines - DON'T PUT YOU DRIVE ON SCSI ID 4
(gripe, gripe).

2/ The Ultra 1 probe-scsi command only works when the machine is stopped
(pressing "Stop-A") BEFORE the machine boots up. NOT that I didn't know
that - only my monitor doesn't actually switch on until the boot process is
well under way. I had been waiting until I could see the screen before
pressing Stop-A.

Anyway, I don't suppose this actually caused "format" to recognise the
drive - unless my previous "boot -r" command was failing. Perhaps this
should be the subject of another huge message on their machines! Well it's
pretty crazy for a 13000 machine.

Anyway, all appears fine - I can now use "format" on the drive - hurrah!

Thanks again for the advice to all who replied.
