I've had similar lack of success trying to blank or overwrite using
cdrecord or growisofs. The disks I'm using are Sony 2X DVD-RW 4.7GB,
which _should_ be compatible with the drive AFAICT. The drive is
happy to write to a new disk.
One possibility is:
$ cdrecord blank=help
Blanking options:
all blank the entire disk
disc blank the entire disk
disk blank the entire disk
fast minimally blank the entire disk (PMA, TOC, pregap)
minimal minimally blank the entire disk (PMA, TOC, pregap)
track blank a track
unreserve unreserve a track
trtail blank a track tail
unclose unclose last session
session blank last session
According to man cdrecord:
-format
Format a CD-RW/DVD-RW/DVD+RW disc. Formatting is currently only
implemented for DVD+RW media. A maiden DVD+RW media needs to be
formatted before you may write to it. However, as cdrecord autodetects
the need for formatting in this case and auto formats the medium before
it starts writing, the -format option is only needed if you like to
forcibly reformat a DVD+RW medium.
Thanks. I'd seen that. I did eventually find the magic incantation:
cdrecord dev=/dev/dvd -v -force blank=fast
The "-force" is the key to getting past whatever it is that my drive
was complaining about. I'm pretty sure I had tried that before and
had it not work, but perhaps the drive had been left in some strange
state by whatever my previous attempt had been.
