The Unidisk 3.5 has four parts to it (five if you count the case):

The Drive itself
Cable
Controller (in the drive)
I/O controller in the CPU

What kind of problems are you having?
The 800k drive is the same drive Apple used in the last Mac Plus's and
Early SE's.  (Apple P/N: 661-0305 or 661-0345)

The Controller board in the drive itself is for the smarts to work with
the older //e 3.5 Unidisk interface board and the Apple //c.

Since the drive Mech's are the same, you can test the drive out on any Mac
(well, I haven't tried an 800k drive assy on anything built since the
Quadra 950).   If you have a IIgs 3.5" drive, you can swap mech's to see
if the drive itself is the problem.
