It doesn't seem to transfer data correctly, If I dump the first couple
megs off a cdrom from my one of my sbpcds and compare it to the dump of
another sbpcd I get no problems, however, when I compare it with the dump
of the scsi-cdrom, which worked fine with a different scsi card, its
completely different. Also, iso9660 gives up trying to mount it.
Whenever I attach a scsi-hd it doesn't seem to read it correctly:

The firewall using an Adaptec 1520 reads these drives fine. In fact, I
pulled this one from it. Any attempts to use the disks end in a slew of
errors.
Thanks.
