really really sure? hm, no, but i am using the no-compression
tape device /dev/rmt/1 as opposed to /dev/rmt/1c:

now, why would that be? if this is an AIT-2 drive writing to a 50Gb
native/100Gb compressed tape? i got the "SDX-500C" string from the
out put of e.g.:
# mt -f /dev/rmt/2 status
Vendor 'COMPAQ ' Product 'SDX-500C ' tape drive:
sense key(0x6)= Unit Attention residual= 0 retries= 0
file no= 0 block no= 0
so, that is really the drive model and not the tape itself; the tape
would really be "SDX2-50C".

well, no i did not do this. i recall doing this for my Eliant-820S.
you are correct that i should do this ;*) it is not that often that
i add an "unsupported" device, so i forgot :*/
