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.
