Severity: important


growisofs fails to blank DVD-RW media, while writing is just fine.

Here is the log :

$ growisofs -Z /dev/dvd -R -J 2005.08.30/

:-[ WRITE@LBA=0h failed with SK=5h/ASC=21h/ACQ=02h]: Invalid argument
:-( attempt to re-run with -dvd-compat -dvd-compat to engage DAO or apply full
blanking procedure
:-( write failed: Invalid argument

using -dvd-compat twice as suggested didn't help at all, as for DAO and full
blanking, the man page doesn't provide any usefull hint on what this means.

Would be nice to have this finally fixed for etch, as i believe this is still
somewhat broken for sarge.
