It's  scsi.  It can read any scsi.  WHat is amazing is how badly iomega
was able to screw it up on the mac.

Just grab an sbc kernel (different scsi driver; the regular has a bug
that's a problem with zips; it solved several days of fighting), grab
the hd/sc aux file from the utilities, and the new mkfs_1.4.  

Start hdsc, then put the zip in (with no driver loaded).  hit partition,
choose ccustom, and delete the mac partition (unless there's space or
another partiton after it.  if so, leave that partition & quit, or put a
1k scratch parttition).

Put in a new mac partition for all but 1k of the space.  THen put a
scratch partition for that 1k.  You *must* put the mac partition before
teh other; mkfs doesn't see the last logical partiton.

Now launch mkfs1.4, put a 32 in where the first 0 is when you get to the
table, let it do its thing, and you're set.  Mount your zip, and be
happy.

again, don't forget 1) the sacrificial partiton, and 2) the sbc kernel;
there are serious (ie, crash) problems on my IIci with the regular
kernel.  and 3) teh number 32.  there is some sensitivity to these
numbers, but 40 & 64 may also work.
