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.

Subject: Disable Tape Compression


I'm using Amanda on Fedora Core 4 with a Quantum SDLT 220 tape drive - I
want
to disable hardware compression but I'm not sure of the best way to do that.

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
