View Full Version : how to do a full format on a partially formatted DVD+RW disc?

I have a (partially) formatted DVD+RW disc, and need to do a full format in order for wodim to be able to properly write to it, since wodim does not do DVD formatting automatically, despite what its man page says. (I want to write using wodim, NOT growisofs, since wodim has a -pad option for zero-padding, and the -pad option to growisofs doesn't work when burning an ISO file.) Anyway,

wodim -v dev=/dev/dvd -format

doesn't work on an already partly formatted disc, only an unused one. And

dvd+rw-format -force=full /dev/dvd

doesn't work either, claiming the command-line option is unimplemented (even though the usage is documented). Is there any natural way to do this, or do I have to do something ugly, like using growisofs to write an exactly 4.7 GB file to the disc?

The growisofs man pages gives the command

growisofs -Z /dev/dvd=/dev/zero

which writes zeros onto the entire disc. Not pretty but it seems to get the job done. I found that cdrskin can't be used either, since it's been unrunnable at least since Fedora 10 - see
