scsi cable that came with the drive. the unit also came with it's own terminator which is also plugged into the
packet loader. The packet-loader is the only device connected to the scsi card externaly.
Inside, the scsi card has both a scsi-1 and scsi-2 connector. The scsi-1 connector has a single device
connected (the CD-Rom). The scsi-2 connector has the rest of the devices connected on a single cable
(3 hard drives, 1 VXA-1 Exabyte tape drive). It is a fairly long cable, with about 8 inches of cable separating each
device. The last device on the cable is the VXA-1 tape drive followed by a termination on the cable itself.
I guess I could go back and try the sym53c8xx-2 driver with more conservative settings on the options and
test again.

As I said, the "library" (autoloader) seems to work The ncr53c8xx driver is the very old one, sym53c8xx-2 is the new one. Actually I've used all 3 of them with a 53c875 on a Linux/PPC box. sym53c8xx-2 (the preferred one) should work fine. > correctly, but it > is just the tape writing that is giving me problems at present.

You already have 6 devices (7 incl. the SCSI adapter), so the cable cannot be that long. How long is it?
