I'm trying to use DVD-RW ("minus RW") disks in my LG GSA-4040B
drive. I can write a new disk just fine, but can't find any way to
blank or re-use a disk. When I run xcdroast and click on the "Blank
CD/DVD+-RW" button, I get "Error while blanking." Here is last part
of the dialog:

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.
Hope this helps.
