Thanks for all the replies - here are some responses....

I now flatout refuse to buy any Quantum 68-pin or 80-pin SCSI drives

firmware is always butchered.
I have recently been playing with Viking II and Atlas IV drives and
have had good success
with them. For example I have 5 Viking II 8.5Gb mounted on a five-drive
shelf in a Quadra 950. They are hooked up to a ATTO silicon express IV
SCSI card. I use one as a boot drive (OS 8.1), and the other four use
REMUS V1.4 s/w to form a RAID 4 array :-)
However, I must admit that these drives came from a former employer who
had bought them new to use in a Linux based server farm. So they would
have had the Quantum standard firmware, which kinda proves your point.
It may be worth checking Maxtor's data sheets for the drives before
you pitch them into a dark corner to see if there are any other ID
setting jumpers on the drive. Most 68-pin drives have them front and
rear.
I checked all that out before - got the datasheet from the Maxtor web
site. But if the firmware isn't standard then my jumper info is
probably useless.
Oddly I have no issues with them on OS X machines. I guess OS X looks
sufficiently like UNIX to throw the firmware a curved ball ;o).
Can't run that on the Quadra 950 - even with a 66MHz PPC upgrade :-)

What I usually do with SCSI drives that give me guff
on a Mac is to low level format them on an Adaptec
2940 PCI SCSI controller in a PC. There's no
operating system involved since it runs from the BIOS
on the controller.
I agree! I'm using a BusLogic device but its the same thing. I always
format and verify on this setup first before going to a Mac platform.
In this case I haven't got that far :-(
If you're converting SCA80 drives to some other type
of connector, make sure the adaptor has jumpers for
setting ALL the functions common on those drives.
These are 68pin and (in the Mac) I'll be using them hooked to either an
ATTO silicon express IV or a FWB JackHammer card, both having 68pin
"wide" connections.
Another important thing is termination power. At most
two devices should be set to send termination power
to the bus.
I'm sure I read it recommended to have all the devices supply power. I
think they are all diode protected anyway so it shouldn't make a
difference

Gregg's point's regarding the jumpers, J3 would be best to configure
the rear one affects the *chain* from what I read. Returning the the
wrong scsi ID seems odd as I don't see why it would be firmware or
what real use such a feature would have ..
On my test PC only one device is attached at a time. I removed all the
jumpers except the small one for termination power, and I used the J3
connector to select termination enable.
Model # please and good luck
One label says:
2275W P/N VK22W012 Rev 04-H
The main label has "Quantum Viking 3.5 series 2.2Gb SCSI DISK DRIVE"
but also the HP logo and "HP P/N D5094-60101"
