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.
Example
# mkudffs --media-type=dvd /dev/dvd trying to change type of multiple extents # dvd+rw-format /dev/dvd * DVD±RW/-RAM format utility by, version 6.1. * 4.7GB DVD+RW media detected. * formatting 9.5\ # mkudffs /dev/dvd start=0, blocks=16, type=RESERVED start=16, blocks=3, type=VRS start=19, blocks=237, type=USPACE start=256, blocks=1, type=ANCHOR start=257, blocks=16, type=PVDS start=273, blocks=1, type=LVID start=274, blocks=2294573, type=PSPACE start=2294847, blocks=1, type=ANCHOR start=2294848, blocks=239, type=USPACE start=2295087, blocks=16, type=RVDS start=2295103, blocks=1, type=ANCHOR
