Ok, i got the drive working, but im not sure why I can't write to it.

[root at cpr]/home/techie(163): camcontrol tur sa0 -v
Unit is ready

I am gettin this in dmesg after i try to write to it:

(sa0:ahc0:0:5:0): WRITE FILEMARKS. CDB: 10 0 0 0 2 0
(sa0:ahc0:0:5:0): ILLEGAL REQUEST asc:24,0
(sa0:ahc0:0:5:0): Invalid field in CDB
(sa0:ahc0:0:5:0): failed to write terminating filemark(s)
(sa0:ahc0:0:5:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM
command to clear this state.

Sorry to keep bothering you all. I'm new to scsi tape drives. :/

Thanks.
