Hi Matthias and all, I tried "sginfo -6 -t 0xf -X /dev/sg0" and "sginfo -6 -t 0xf -XR /dev/sg0 0 1 1 0 3 3"
and it worked after ejecting the tape. Tomorrow I can insert a new tape (the drive is some kilometers away) and test it by "mt -f /dev/nst0 datcompression", which works only with a tape inserted. mtst and sg_wr_mode are not available on my SuSE 9.1. I think I will update it soon :-) Thanks again!
