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 defaults.

       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' 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

       -o offset
              Set write offset.

BUGS         top

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