Hello,

I'm having a terrible time trying to get my Fujitsu 2624SA drive to
work on my NeXTstation color.

I had the drive working on a IIcx for about 8 months without a
problem, but there are several strange things about the jumper
settings. 

First of all on CNH1 jumper 5-6 was shorted when the drive was on the
Mac. According to the drive manual, this meant that that drive was
supposedly in diagnostic mode.  Well it worked fine (i.e. in normal
operation mode).  But when I moved it over to the NeXT, I got SCSI
parity errors, so I opened that jumper (of course powering down the
drive and NeXT first).  All other jumpers are shorted except 15-16
which disables synchronous transfers.

The problem is that the drive will not spin up unless jumper 5-6 is
shorted. (Which on the NeXT does seem to put the drive into a
diagnostics mode).

Thoroughly confused...thanks for any help,
Todd

I've figured out the problem.  Even though the Fujitsu "Technical
Handbook" lables the jumpers from left to right (on p. 3-7), in
actuality they are numbered from right to left on the drive (As shown
by the diagram on p. 3-5).

Also the manual shows CNH7 as only having four pins, my drive has 5.
Took a bit of experimenting to get the SCSI id set.

FYI, my NeXT did successfully mount the drive as an Apple formatted
drive, but it only mounted one partition.
