The ADU driver trick is supposed to be used with a third-party driver
in the GenericMacSCSI file.  My local user group came across one
driver that supported SyQuests and also seemed to work with most other
SCSI drives, but I forget its name.
The driver included in ADU is only guaranteed to work with
Apple-branded SCSI drives.  It may or may not work with other drives.

It sounds like the Mac driver created a large number of 'spare'
entries in the partition map, possibly with some invalid data that
caused the IIgs SCSI drivers to get very confused.

I would be interested to know what the 8-bit program "Chinook SCSI
Utilities" thought of the drive.
