[ILUG] SCSI disk not detected

First off, thanks to everyone for all the suggestions

pretty sure I'm ok there. the only other scsi stuff on that chain are 
the two disks you see in my earlier posting.

yes, this works fine.  the SCSISelect utility that it pops up sees 
the drive without problems.  It even offered to format it for me 
(assume that is low level) which I let it do as I was hoping that it 
needed this before it would be detected ok.  

anyway the disk seemed to go through the format ok (lots of flashing 
of the led etc... but it didn't help with the detection).

Yes, there are two controllers.  The second one is Ultra as-opposed 
to Ultra2 (i should add that i know next to nothing about scsi 
controllers/devices...).   The disk is Ultra2 so it needs to be on 
that controller..  I'll give it a go on the other controller next 
week.

Thanks again to everyone for the suggestions, much appreciated.
