I used Hard Disk Toolkit PE which I got with a hard disk I ordered; it did
not require that I replace the driver.  (It loaded a temporary driver to
work with the disk.)  In the Iomega Drive Options program, which is part
of the Iomega Tools, you can turn on/off such things as verify disk writes,
eject at shutdown and eject on restart.  I turned all off, and did not have
the problem of the disk ejecting when I started NetBSD.

The Tools program will run if you've run the Iomega Guest program.  I just
tried it, it tells me there's no disk in the drive and patiently waits for
me to put one in...


I eventually gave up on running off the Jaz drive for an entirely different
reason -- my hardware seems to be flaky.  I have a full '040 on my C610
(uses the esp SCSI driver, not sbc or ncr), was able to get NetBSD installed
and the drive cleaned and start running.  When I tried to build the world,
it'd get partway through and start getting major disk corruption.  I'd try
a regular hard drive to see whether it's the Mac or the Jaz, but I don't
have an available one that's sufficiently large...
