I did it by 'su amanda -c "/usr/sbin/amtapetype -c -e 20g -f /dev/nst0' > Might you have somehow mucked with the tape's blocksize when > you turned off compression?

I tried 512 bytes (SLR7 default), 32768 (Amanda default), but I did not try "0" yet.

That exactly was my motivation. I am very happy with SW-Compr. with different DAT/DLT drives, and the SLR7 was a horn in my side. I can't change the drive, and if I can't change the compression in a working manner I will have to go back to hw-comp (even if I do not like it). Thanks for your advices!
