I use several type of tapes; from 1Gb to 20Gb tapes. I can read and write from of them but DDS-4 (20Gb)! I can read DDS-4 btu cannot write on them. When I try to write on a DDS-4 I encounter an error: [gueway] ~# tar c / tar: Removing leading `/' from member names tar: /dev/sa0: Wrote only 0 of 10240 bytes tar: Error is not recoverable: exiting now and /var/log/messages says: Jun 5 12:28:09 gueway /kernel: (sa0:sym0:0:5:0): WRITE FILEMARKS.

I do not understand why i can write on DDS-2 or DDS-3 but not on DDS-4 (i used to several months ago). I need your help ;) Thanks Phil.
