This drive or media does not support the 'BLANK media' command cdrecord: Cannot blank disk, aborting.
These lines say it all, see the BLANK command applies to CDs, not to DVD-rw's ("cdrecord --help"). Usually you *format* these media once, then, unlike CDs, you simply overwrite them.
I hardly use optical media these days. But I happen to find an old Philips DVD+RW disk in a drawer. I used the cdrecord -v blank=all command on it and it worked just fine. I didn't save the output it created but there was a HINT telling me I really should be using the dvd+rw-format command.
I err'd when I wrote the above as I actually found 2 DVD's in the drawer and the one I used was an off-brand from "Melody Group" here in Taiwan and blanking worked.
The Philips brand DVD+RW does *not* support the "blank" option when using the dvd+rw-format tool...
[egreshko@meimei ~]$ dvd+rw-format -blank=full /dev/sr0 * BD/DVD±RW/-RAM format utility by appro@fy.chalmers.se, version 7.1. * 4.7GB DVD+RW media detected. - illegal command-line option for this media. - you have the option to re-run dvd+rw-format with: -lead-out to elicit lead-out relocation for better DVD-ROM compatibility, data is not affected; -force to enforce new format (not recommended) and wipe the data.
But, if using cdrecord -v blank=all it will proceed....but I killed it before it started to wipe the disk since I found I wanted to keep the movie that was on it. :-) :-)
