OK, that narrows things down QUITE a bit. I worked with
drives and others that had a lot of constraints on what you
and you could do some interesting things. I think you could
zero-length blocks, and they would show up just like that when
read. Clearly on 9-track, there SHOULD BE no such thing as a
zero-length block, but I suppose some drives could actually
such a thing at 1600. A preamble, CRC, LRCC and postamble, with
no data. But, that OUGHT to be an illegal command.
