I didn't see the start of this thread - what exactly is the question?
Last year I posted fairly trivial patches for the T4000s, which I
thought had been incorporated but I'm still running 2.1.5 on the
relevant machine.

It is the right density code, but the drive doesn't have hardware
compression.

Maybe the standard is out of date :-) Incidentally, the QIC standard
(whose number escapes me) for Travan-4 does not specify how it is
accessed as a SCSI device; I believe there is another standard (which
I don't have) concerning SCSI implementation of QIC standards.
