Hi!
I'm new on this mailing list, and this is my first message here, so
please bear with me somehow... :-)
OK, in short, my problem is that Linux or aic7xxx driver somehow
cannot recognize my SCSI hard disk. The hard disk is seen, but not
recognized. Important thing here is that disk is recognized by the
SCSI controller (Adaptec 2940, not Ultra, not Wide), and works fine in
Windows. Now, the details:
Adaptec BIOS:
SCSI ID #0 - QUANTUM TRB850S - drive 82h
SCSI ID #2 - QUANTUM FIREBALL ST3.2S - drive 83h

This is the sitaution. As I said and as you can see, the hard-disk is
seen (scsi:0:0:2:0), but not recognized as a Quantum Fireball, and is
not attached to a device (probably /dev/sdb), so I can not communicate
with it under Linux.
A tried a lot of things. I used kernel 2.2.15-1.0.0, with 5.1.19
(IIRC) version of the aic7xxx driver, it didn't work. I upgraded my
kernel to 2.2.15-1.5.0 with 5.1.25 driver verison, it didn't work. I
patched driver to 5.1.27 version, no luck. I compiled driver as a
module, no luck. I turned off TCQ, same story. I changed termination,
disabled parity and did all I can imagine with Adapted BIOS options,
all with the same result. I changed the ID's, I plugged out other,
properly working, SCSI deviced, I left this hard-disk to work alone on
the cable, and again no luck with it. I'm pretty much out of ideas.
The biggest paradox of all is that everything's working fine under
Windows, so I think we cannot talk about faulty disk/cable/controller.
HELP! :-)
Is there any chance I can get this hard disk working under Linux, or
should I simply - change the SCSI controller? If any of you have any
ideas, please share it with me, I would be very thankful. Thanx in
advance and bye!
