OK.  That narrows down the scope somewhat.  The next obvious potential
problem: have you installed the SCSI drivers on your system disk?  If
not, ADU will not be able to do a thing.

Use the Installer to add them, or just copy the SCSI.MANAGER and
SCSIHD.DRIVER files from :Install:System:Drivers to the same directory
on your system disk.  You might need to delete something to be able to
fit them.

Another option is to boot from the Installer disk, then quit from the
Installer and use the GS/OS program selector to launch Advanced Disk
Utility.

Obvious problem number two: is the slot containing the SCSI card set to
"Your Card" in the Control Panel?  Which slot is it in?


In ADU, you should be able to locate the Connor drive by clicking on
the Volume (Disk?) button a few times (it cycles around the online
volumes).

If it doesn't appear, there are several possible causes:

1. Your SCSI card doesn't actually have the Revision C ROM.  Check the
label.  It should read 341-0437-A.   Any other number is an older
version, and will not be recognised by GS/OS.

2. There is a cabling, termination or termination power problem.  The
original Apple SCSI card is not terminated, and doesn't supply
terminator power.  You should have a single terminator connected after
the Connor.  If you need to connect a second drive at a later stage,
you need a terminator before the first drive and another after the last
one.  At least one of the drives must supply terminator power.

You could also try removing all termination.  I wouldn't recommend
running in this configuration, though.

3. There is a problem with the SCSI IDs.  Make sure the Apple SCSI
card has the ID jumper set on the rearmost jumper pair, setting it to
SCSI ID 7.  The Connor must be set to any SCSI ID other than 7.  If all
else fails, try changing the computer to SCSI ID 6, in case the drive
is stuck at ID 7.

4. The Connor is incompatible with the original SCSI card or the IIgs
(not likely).

5. The Connor has already been formatted or partitioned, and is not
recognised by the GS/OS drivers or ADU.  I don't think this is
possible: it should appear as something, at least giving you a warning
message about an unrecognised file system.

6. Something is faulty.
