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" -
