I'm going to take a big SWAG and wonder aloud if you have a (Plextor)
CDRW drive out there at SCSI ID4. I had the same problem...

The newer Adaptec drivers in the 2.4.x kernels (including .17, BTW, as
well as 2.2.20) are VERY picky. I had to yank my CDRW out and can only
use it on my Alpha box at home or here at work, both of which use the
Q-Logic SCSI boards. However, Symbios/NCR/LSI Logic-based SCSI cards
(e.g., the Tekram boards), are likely to work as well. No amount of
horsing around with Multiple LUN support, etc., etc., in the kernel
configuration menues seemed to work around this problem, and there was
some discussion in the Linux Kernel Mailing List about it a few months ago.

Either that, or as someone else suggested, you may have a SCSI termination
problem. You need to make sure that you have precisely two terminators, one
at each end of the SCSI bus (and the Adaptec board may or may not be
necessarily at one end of the bus, BTW - check the jumpers, etc.). That is
probably the biggest 'gotcha' about SCSI, and not just on PCs :-).

HTH,
