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.
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.
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" -
