Fair enough. Those should be supported, but the driver you're using was
made without any support from Adaptec and had to be reverse-engineered. It
may have some bugs.
That being said, have you used these SCSI disks with this adapter before,
with DOS or Windows? Adaptecs have a reputation for being very sensitive
to cabling issues. If the cables aren't set up just right, they can get
flaky. Especially if you're doing Ultra SCSI, you have to make sure that
you've got active termination, and it's terminated in the right places.
The SCSI-HOWTO is currently unmaintained (something I'm hoping will be
remdied soon) but still useful. Take a look at:
ftp://sunsite.unc.edu/pub/Linux/docs/HOWTO/unmaintained/SCSI-HOWTO
This will give you enough information to make sure that the cables are
set up right. After that, you need to look at how the card is set up in
its BIOS (the Ctrl-A setup screen) and see if maybe you have an
unsupported option enabled or something.
