Sorry to keep this thing dragging on.....

but if someone knows the answer to this, i can refrain from
future postings.....

I bought a quantum 80S from a Mac dealer... the "bare" drives
they get from Quantum are apparently already set up to run on the
mac.... ie., there was a jumper on one set of pins and the drive 
seemed to be formatted for a mac already.... leaving the jumper
where it was , i couldn't get Supra to format the drive.  I have
the latest version of the software which recognized the drive...
so i know it is not the software.  Putting the jumper on other 
sets of the pins either kept the drive from even spinning or 
failed to allow formatting.  Removing the jumper also failed
to allow formatting.  As i have no idea what the jumper 
configuration should be, i am hoping that someone who is actually
using the Quantum 80S with Supra Host could fill me in on the
pin configuration.   Below is a diagram of the pins and the jumper
set when i received the drive in the mail.  (my Atari dealer has
never worked with this drive before.... so he is at a loss as much
as i am....)


A0 .  .   
A1 .  .     SCSI pins
A2 .  .
