Just for your information, on my Linux mtx's version (Slackware 8.1 with a
2.4.18 kernel) there is no such option "nocompression" to mtx... But there
are the options defcompression and compression which can be set to 0 then
it looks like that compression is disabled...

PS: thanks Joshua for your help

Regards

Under Linux you can call the following to disable compression.

      mt -f /dev/st0 nocompression

The other method would be the disable a DIP switch or jumper on the
tape drive.

I include the above line in my startup scripts. It would appear it
only needs to be set at boot.
