I suppose that means ADU v1.1 lacks the driver, unlike ADU v1.2.
I didn't know that, but I suppose it makes sense because HFS was
not introduced as a GS/OS file system until System 6.0 and v1.1
came with System 5.x.

I think DOS FAT and IIGS/Mac partitioning systems store the
partition data in different areas, which is why both can remain.

What I suggest doing is low-level formatting the drive on a Mac,
completely obliterating all partition data so you have an empty
drive.  Then you can try ADU v1.2 with the GenEx extracted
driver one more time.

Mac and IIGS partition data is the same, so formatting on one
will definitely kill the other.  If you must do it on the 486, one
thought is to fill up the drive under DOS.  Just copy a bunch
of junk files to it until it fills up.  That should obliterate the IIGS
ADU v1.1 partition data too.

Also, what kind of SCSI card do you have on the IIGS?  I've
read that the Ramfast does not like ADU.

Lastly, is the drive properly terminated?  Sometimes termination
problems causes SCSI voodoo.  Check SCSI ID settings and
hunt for any conflicts.
