First: The pt driver DOES NOT support the mt command sequences.
Second: It appears that your tape is in the "locked" mode. You need to
check your tapes and make sure that they are "unlocked".
Third: Get an eval copy of BRU and setup the Non-Rewinding drive
(/dev/npt0).
I have a HP 8Ge drive and wish that the pt driver would work with the 'mt'
command set. Maybe it is time for me to look at the ide-tape driver, which
supports these commands.
