Are there any dip switches on the drive ? My HP DAT24x6 has a dip switch bank on the bottom which turns off compression in the HW. I don't see any indication of that in your drives manual.

I can issue a command mt -f /dev/nst0 defcompression 1 which seems to work (amtapetype doesn't give me the warning about hardware compresion) but as I understand it this change goes away as soon as I change tapes. Meaning each time I insert a new tape I have to re-enter this command? How can I make the change permanent so that I don't have to worry about manually changing a settting? Any ideas or help would be much appreciated. Chris
