OK, so summary messages are a hangover from other lists, but I think they're
a good idea :-)
I originally wanted to get an old Sun DDS 1 drive to write tapes that could
be read on a WangDAT 3100, but they appeared to default to "compressed".

This seems to have done the trick marvelously.
"mt status" reported a default density of 0x8c and using the "setdensity 0"
command now allows my WangDAT 3100 to read tapes created on this drive.
Thanks to everyone else who responded to this query.
It looks like the recent "mt" command can set a _LOT_ more than the version
I learnt oh-so-many-years ago :-) :-)
