If anyone has a Quantum ProDrive 170S working on an A3000, I'd
appreciate some help. 

I just got the drive earlier today (from Alliance Peripheral Systems,
highly recommended! Fast service, and low prices), and have not been
able to get it working 100% yet.

Everything seems to be working just fine, and then I get a lockup of the
whole SCSI bus. I've got the stock Quantum 100S addressed at 6 (where it
came from CBM), a CDC Wren III addressed at 0, and the Quantum 170S
addressed at 1. 

The Q170S seemed to run through low-level format, partitioning, and
AmigaDOS format just fine, but when I was copying a partition on the
Q100S to the 170, it locked up. I then pulled the 100 from the system,
jumpered the 170 to 6, and ran the whole A3000 install procedure on the
170. It worked perfectly until the last step ("Setting up Icons") when
it locked up again. It has had other random lockups and read/write
errors as well.

There are three jumpers on the drive I don't understand: SS, EP & WS.
The Q100S had EP jumpered, and the other two open, so I set the Q170S up
the same way. What do these jumpers do? Do I have them right?

I've since hooked the Q170S to the HardFrame controller in an A2500/20,
and it seems to be working perfectly. Unfortunatly I want to put the
Q100S in the A2500, and use the Q170S as the A3000's primary drive.

Am I crazy? Can anyone help me?


Oh, one more thing. The Q170S is capable of synchronous SCSI, and so is
the A3000. Does anything exist yet that will allow me to enable
synchronous mode for the Q170S (and not attempt synchronous mode on the
Wren III)?

Since esunix has been very flakey on news lately, I'd appreciate it if
you could respond by e-mail. I'll summarize all the good news I get.
