Beware that *many* DDS1 drives cannot do
variable-sized blocks very
well... if memory serves me right, RSTS BACKUP format uses many
block sizes in a single backup file:
80 - ANSI header
14 - RSTS file header
1024
2048\__ data block sizes, often +4
4096/
8192
This might be your problem.. even though the tape image is
fine, the drive doesnt let you use arbitrary block sizes.
This may or may not apply to your drive.. Nico might know
more about this- I just ran into this when writing an ASPI
layer for my software... I was unable to tell the DDS drive
to switch to 64-byte blocks.. it insisted on 512-b blocks.
Interesting.... BTW, the DDS1 drive I'm using is a DEC TLZ06. Any idea if
this might also be a problem with an Exabyte 8500 tape drive? It would be
easier for me to attach an Exabyte 8500, than it would be to get a TZ30
hooked up. Well, maybe not that much easier, I think all the tapes are
buried in the same spot :^/
