Jon,
It is not always the case that the record length for a save set will
be 8192. That is the default value for save sets written directly to
tape. Save sets written directly to disk use 32760 (I think). The
value can be specified in the backup command.
Right, should have made it clear you need to know the block size from
when the tape
was read to be able to supply the correct number to the program.

Steve,
"Direct-access tape support": do you have any suggestions on a USB to SCSi
adapter that I might try testing my TZ30 tape drive on my Mac Mini (Intel) under OS X
10.6.8? Not that I think I can get to it soon (some employment is needed...), but so I
can look for hardware that might serve the purpose.
Never heard of such a device, although I can see the usefulness. I have
used some
old SCSI tape drives on Linux using an Adaptec PCI-SCSI adaptor, and it
generally
works. Some old drives don't support SCSI-II and so the driver searches
for commands
that are acceptable to the drive.
Jon
