DESCRIPTION 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 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.

-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.

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

-p type Set packet type. Either 0 or 1, corresponding to variable and fixed packet sizes respectively.

-o offset Set write offset.
