       The  cdwrtool  command can perform certain actions on a CD-R, CD-RW, or
       DVD-R device. Mainly these are blanking the media, formating 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.


       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.

       -s     Set  write  parameters  determined by -l, -w, and -p options for
              the disc.
              (Note by your Debian maintainer:  Apparently  this  option  does

       -v version
              Specify  the  udf  revision  to use. Valid revisions are 0x0201,
              0x0200, 0x0150, and 0x0102. If omitted, mkudffs  udf-version  is

       -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’  respectively.

       -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.
