To check:   mt -f /dev/nst0 datcompression
To disable: mt -f /dev/nst0 datcompression 0

Probably yes, unless you can find a jumper that disables compression
once and for all.  This discussion has been held several times before;
you'll find answers with excruciating details in the archives.  Gene H.
for instance, has posted on several occasions, a complete write-up on
the caveats of hardware compression, which you should read even if it
does not necessarily apply to our LTO-2 drive, just to know what can
happen.
