Hi Listers,

Just to give my 0.02EUR

mt -f /dev/nst0 defcompression off (or 0 depending on your mt)
mt -f /dev/nst0 compression off (or 0 depending on your mt)

I am running SuSE 9.3 and the only available mt operation is
"datcompression"

See:
athene:~ # mt --version
GNU mt version 2.5

You need the "mt-st" program (or maybe "mtst") that does implement
the above controls.

BTW: Is it true that a tape formerly written with hw-compression will
"override" the 'drive compression off setting' because the compression
on/off status has been written on the header of the tape? If yes, I should
"reformat" a lot of tapes as described by Gene :-/

At least some versions of linux had it.  In my current environment
I cannot reproduce it anymore.
