How to format a DVD with UDF

This document assumes you already have UDF support, either built into the kernel or as a module.

To format a DVD at /dev/dvd with the UDF filesystem, use the mkudffs command:

mkudffs /dev/dvd

If that fails with a 'trying to change type of multiple extents' error, then it's likely that you've got a virgin disk. If you have the dvd+rw-tools package, you can re-format it with the following command:

dvd+rw-format /dev/dvd

Then run the mkudffs command again.


# mkudffs --media-type=dvd /dev/dvd
trying to change type of multiple extents
# dvd+rw-format /dev/dvd
