Hello ClassicCmp and Port-vax,
I am trying to track down the compatibility of the VS3100/MS SCSI bus with
"modern" SCSI drives. The case in point is that I'm trying to connect a
SeaGate Barracuda (ST32550N) drive (2.54GB SCSI) to the internal bus,
replacing a 426MB Seagate drive. When the drive is installed the system
gets indigestion. I'm currently attempting to disable parity on the drive
in case that is an issue.
Has anyone done something similar? Is there some caveat I've missed?
Obviously the DEC manual isn't much help :-)

One obvious thing to mention... System drive maximum 1.3 gig or less
I believe.

I can tell you of some that won't work. I've got several DEC
DSPs, Seagate STxx's, and others which are just fine on
other systems but NG in my m76.
There was some reference recently, either here or on usenet
as to the reasons why. Maybe someone else can recall these.
I finally relented and bid on an RZ26 on eBay. Should be here
Any Day Now. Seems that the RZ series work just fine with
the Vaxstations.

Hello Chuck
Check for 524 byte sectors. Esp if drives might have been used on
AS/400's or other similar transplanted martian technology. There is VMS
RZDISK.EXE which can correct 524 byte sector problems, not sure for the
BSD's.

If the host adapter does not 'know' parity, the drive will most likely not
appear to exist at all to it. I would think small-word-scsi. A lot of old
scsi host adapters and disk controllers don't know how to handle the
parity bit and just fart.

Interesting, I tried the internal format (Test 75) and got a couple of
errors so on a whim I swapped it out with another one (who wants a SCSI
disk with bad blocks anyway?) and the replacement works fine. No errors,
nice and quiet. I returned the first drive to the guy who sold it to me and
got a replacement.
The best clue seems to be that the "bad" drive wouldn't show its size in
SHOW DEV but the good drive does. I've written off the drive as bad and am
off making more progress.

Today I retired a Seagate ST31200N from a 2100; it lived inside
the cpu box for quite a few years. I remember that the jumper
marked "PE" was installed.
