Hi Kiley,

Can you post the listing of the "format" command?
It should print something like:

Searching for disks...done

       0. c9t0d0 <ATA-WDCWD5003ABYX-1-1S02 cyl 60797 alt 2 hd 255 sec 63>
       1. c9t1d0 <ATA-WDCWD5003ABYX-1-1S02 cyl 60797 alt 2 hd 255 sec 63>
Specify disk (enter its number):

(Just hit Control-C to return back to the command line.)

This should give you a listing of all the drives you have available on
your machine. If c9t17d0 isn't there, then there's a good chance that
you'll need to run something like "devfsadm -c disks" to force a SCSI
bus rescan (to discover new drives).
