Thanks again for your replies Michael and Ron.
In answer to your questions Michael:

When I run the command lsmod I get the following:
# lsmod

I have tried running tar, cpio, dump, etc from the command line and have
also tried from a terminal session under X11.

Why then when I boot the machine into MacOS 9 do the backups run without
any problems using Retrospect?

How do I do this? The SCSI adapters are:
SCSI Bus 0 - Apple Computer MESH
SCSI Bus 1 - Apple Computer NCR53c96
The SCSI configuration shown from SCSI Probe under MacOS 9 is:
SCSI Bus 0 - ID=0 Vendor: SEAGATE Model: ST32550N Rev: 3705 -
Hard drive
SCSI Bus 1 - ID=2 Vendor: ARCHIVE Model: Python 02830-XXX Rev: 5.76
- Tape Drive
ID=3 Vendor: MATSHITA Model: CD-ROM CR-8005A Rev: 4.0i - CD-ROM Drive
ID=4 Vendor: FUJITSU Model: M2684S-512 Rev: 2026 - Hard drive
ID=5 Vendor: COMPAQ Model: ST15150N Rev: 5217 - Hard Drive
ID=6 Vendor: COMPAQ Model: ST15150N Rev: 5217 - Hard Drive

Again, when I boot the machine into MacOS 9, why then do the backups run
without any problems using Retrospect?

Does this mean that even though SCSI termination may work fine under
MacOS it may not under Linux?
