I just got a 1.3Gig Pinnacle Micro Sierra MO drive to play with, and am
seeing some strange problems.  I'm on the i386, using the AIC-6x60 driver,
but feel this is probably a generic SCSI thing if it's a NetBSD problem.

The basic problem I see is a "sd1: illegal request (data ...)", when writing
to sd1, which is the MO drive.  A couple times this has proved to result in
data on sd1 being different than the data being copied to it, and just now
my machine locked up after I issued a "cp /usr/local/bin/* ." (. being the one
FS on the MO drive).  It seemed to copy OK until I got the illegal request 
and then went out to lunch.

I copied about 200 Meg to the flip-side of the cartridge in DOS, so the SCSI
cabling and termination should be OK [sd0, an internal drive is terminated as
is the MO drive... My SCSI card seems to be missing resistors to remove, but
I assume it must be smart enough to do something right... (?)].

Anyway, here's a snip of my messages from before the lockup:
