Has this drive ever worked?  If it has been de-cabled, or the lead drive
has been removed, check the cables again.  Make very sure that NONE of the
pins are crossed over.  If any of the ground lines are crossed, or not
making contact, the drive may register (become available), but you won't be
able to do anything with it.  Check the terminators as well, and any place
where the cable may have been disconnected.  Those cables are very easy to
bend pins on!

If it was functioning and quit, and has not been disconnected, you may have
a problem in the interface card pack on the drive.  Also make sure that
the interface you are connected to on the drive says it is online on the
front panel.  You can also rmdev the drive and do a mkdev on it to see if
it comes back.

If all else fails, have your CE run a SCSI wrap test after running card
diags on the drive.

just some thoughts.
