DESCRIPTION

       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 defaults.

       The usefulness of most of the options is not explained.

OPTIONS

       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'
              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.

BUGS

       Many  modern drives refuse on the preparations to format new, blanked, or appendable CD-RW
       media. This causes a message like

              Command failed: 55 ... - sense ...

       The remedy is to use a CD-capable burn program for  writing  a  session  and  closing  the
       medium.  For  example  by  using  any  of  "cdrecord", "wodim", "cdrskin", or "xorriso -as
       cdrecord" as content of variable prog in:

           prog="xorriso -as cdrecord"
           drive="/dev/sr0"
           dd if=/dev/zero bs=1M count=10 | $prog -v -eject dev="$drive" -
