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" -
