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.
