DESCRIPTION         top

       The cdwrtool command can perform certain actions on a CD-R, CD-RW, or
       DVD-R device. Mainly these are blanking the media, formatting it for
       use with the packet-cd device,  and applying an UDF filesystem.

       The most common usage is probably the `quick setup' option:

              cdrwtool -d device -q

       which will blank the disc, format it as one large track, and write
       the UDF filesystem structures.

       Other options get and set various parameters of how the device is set
       up, and provide for different offsets, modes and settings from the

       The usefulness of most of the options is not explained.

OPTIONS         top

       Main directives:

       -d device
              Specify the device to use. eg. /dev/sr0

       -i     Print disc track info.

       -g     Print write parameters.

       -u length
              Make a UDF filesystem using length number of blocks.

       -q     `Quick setup': blank the disc, format it as one large track
              and write a UDF filesystem.

       -m offset
              Format the disc at offset number of blocks.

       -b mode
              Blank the disk using a mode of `full' or `fast'.

       -f filename
              Write file.

       -c track
              Close track.

       -r track
              Reserve track.

       -z length
              Fixed packet length.

       -s     Set write parameters determined by -l, -w, and -p options for
              the disc.

       -v version
              Specify the udf revision to use. Valid revisions are 0x0201,
              0x0200 and 0x0150.  If omitted, mkudffs udf-version is 0x0150.

       -h     Prints a sparse help message.

       Write parameters:

       -t speed
              Set write speed. (Defaults to 12x ?)

       -l type
              Set multi-session field. Either `0' (default), `1', or `3',
              corresponding to `No B0 pointer. Next Session not allowed',
              `B0 pointer = FF:FF:FF. Next session not allowed', and `Next
              session allowed. B0 pointer = next possible program area'

       -w mode
              Set write mode. Either `mode1' or `mode2' (default).

       -p type
              Set packet type. Either `0' or `1' (default), corresponding to
              variable and fixed packet sizes respectively.

       -o offset
              Set write offset.
