You can as well use dvd+rw-format -blank=full to apply full blanking procedure to DVD-RW media. I personally actually recommend to format for Restricted Overwrite instead. It's simply more practical: - no full blanking is required if you want to reuse media; - ISO9660 volume is grown within single session, no multi-border support is required for playback in legacy DVD-ROM units; - no media capacity is spilled on border-out/-ins; > but it looks like both sessions need to be an isofs. Why do you think it's called grow*iso*fs:-) > now i am trying to write multiple tar archives to the dvd media as multi > session and it is failing. Even if you manage to put one tar per session, how would you access the second tar? If you want to "tar-format" DVD media, multi-sessioning is not an option, isofs is the *only* working option for multi-sessioning. > my first command: > # tar cvf - /tmp | growisofs -Z /dev/scd0=/dev/fd/0 > works great, exactly what i hoped for. i am able to get the data back > from the media using: > # readcd dev=0,0,0 f=tarpipe | tar -tvf tarpipe What's wrong with 'tar tvf /dev/scd0'? > my second command and its output: > # tar cvf - /opt | growisofs -M /dev/scd0=/dev/fd/0 > :-( /dev/scd0 doesn't look like isofs... > > does this imply that there has to be an isofs on the disc to append to > it? Yes. Once again, isofs is the *only* working option for multi-sessiong. Well, it's not 100% true, but it's the only *practical* option and the only one I'm ready to discuss:-) > growisofs did not seem to care that the first image i wrote was not > isofs No, it didn't and it's intentional.
