I still have one of these.  It was my third hard drive for the IIgs
(Rodime 60MB, then a SyQuest SQ-44, then the Quantum).  The current
drive is a Quantum Trailblazer 850.

If you use ProDOS-8 2.0.1 or later (System 6.0.1 includes P8 2.0.3) then
you can get a maximum of seven partitions with the original Apple SCSI
card, or as many as you like with the Apple High-Speed SCSI card
(limited by ProDOS's 14 unit maximum, reduced according to the number of
other slots containing drive controllers).

Aha!  You have a SCSI ID problem: the drive and the SCSI card are set to
the same ID, which causes the computer to see another instance of the
drive for each possible SCSI ID (seven instances).

Check the jumper/switch settings on the card and drive.  The recommended
setting for the computer is 7, and the drive can be anything else (it
will boot faster for higher numbers, so I'd recommend 6).  The other
factor is that the Apple cards always boot from the highest numbered
drive, so if you intend to connect another device, the regular hard
drive should be as high as possible.
