CDRWTOOL(1) Commands CDRWTOOL(1) NAME
cdrwtool - perform various actions on a CD-R, CD-RW, and DVD-R SYNOPSIS
cdrwtool -d device -i | -g cdrwtool -d device -s [ write-parameters ] cdrwtool -d device -q [ write-parameters ] cdrwtool -d device -m offset [ write-parameters ] cdwrtool -d device -u blocks [ write-parameters ] cdrwtool -d device -b b_mode [ write-parameters ] cdrwtool -d device -c blocks [ write-parameters ] cdwrtool -d device -f filename [ write-parameters ] cdwrtool -d device -r track [ write-parameters ] cdrwtool -h 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. -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. -s Set write parameters determined by -l, -w, and -p options for the disc. (Note by your Debian maintainer: Apparently this option does nothing.) -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' (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. AUTHORS

NEWFS_UDF(8) BSD System Manager's Manual NEWFS_UDF(8) NAME
newfs_udf -- construct a new UDF file system. SYNOPSIS
newfs_udf [-Ndeouw] [-b block-size] [-D defect-file-name] [--dup-meta-part-file] [-E ecc-in-blks] [--enc encoding-name] [-v vol-name] [-m media-type] [--meta-part-alloc-unit n] [--meta-part-align-unit n] [--meta-part-init-size n] [-p packet-size] [-r rev] [-s size] [-S start-block-address] [--spare-blks n] [-t access-type] [--unalloc-spc blk-addr num-blks] [--wipefs yes|no] [--userid uid] [-U uid] [--groupid gid] [-G gid] special DESCRIPTION
The newfs_udf command builds the UDF filesystem on the specified special device. The options are as follows: General options: -N Causes the file system parameters to be printed out without really creating the file system. -w Stop processing on warnings, default: no --wipefs yes|no Whether wipe existing file systems on the volume before formatting it. Default: wipe existing file systems when media-type is block device (blk), access-type is overwrite (ow), and the Keep Disc Open option (-o) is not specified; do not wipe existing file systems by default in all other cases. --largesparse Format the volume to use a non UDF-compliant format to efficiently support very large sparse files (up to 2^63 - 1, or 9,223,372,036,854,775,807 bytes). Sparse files on this volume that has holes larger than 1GB cannot be accessed by other UDF imple- mentations. Disc properties: -b block-size The block size of the file system, in bytes, default: the native block size of the device, or 2048 for an image file -d The file system manages defects by creating a sparable partition, default: no -e Use extended file entry instead of file entry, default: no -E ecc-in-blks ECC block size in number of blocks -m media-type The type of the media, can be blk (block device), var-packet (varible size packet writing), fix-packet (fixed size packet writing), or pow (pseudo overwrite), default: blk -t access-type The access type of the partition, can be wo (writeonce), ow (overwrite), or pow (pseudo overwrite), default: ow -o Keep the disc as open by only writing the first AVDP (e.g., background formating haven't finish, so the write of the last two AVDPs is not possible), default: close the disc for overwrite media, and keep it open for write once media -p packet-size The size of a packet in number of blocks, default: 1 -s size Size of the file system in blocks, default: size of the device UDF parameters: General: -r rev UDF version number, can be 1.02, 1.50, 2.00, 2.01, 2.50, or 2.60, default: 2.01 -u Creates unique id table (or unique id stream), default: no --unalloc-spc blk-addr num-blks Unallocated space recorded in unallocated space descriptor, default: no unallocated spc -v vol-name Volume identifier, max 127 ascii or 63 unicode chars, default: "Untitled UDF Volume" --enc encoding-name The character encoding of the volume name, can be "utf8" or "utf16", default: utf8 Virtual partitions (for CD-R, DVD-R SL/DL, DVD+R SL/DL, and HD DVD-R SL/DL): -S start-block-address The start block address of the last session. Newfs_udf will search for this value for optical media Sparable partitions (for CD-RW, DVD-RW, and DVD+RW): --spare-blks n Total number of sparing blocks (2 sparing tables are always used), default: 128 -D defect-file-name The name of the file containing all defect blocks. This file is a text file, contains the physical block address of the media that has defects. When one block of a packet is defective, the whole packet is marked as defective. The block numbers in the file is delimited by space. Multiple numbers can be on the same line. Metadata partitions (for BD-R with POW, BD-RE and other overwritable media with UDF 2.50 or higher ): --dup-meta-part-file Duplicate the content of the metadata file in the metadata mirror file, default: no --meta-part-alloc-unit n The allocation unit size of the metadata partition in number of blocks, default: max(32, eccSizeInBlks, packetSize) --meta-part-align-unit n The alignment unit size of the metadata partition in number of blocks, default: max(eccSizeInBlks, packetSize) --meta-part-init-size n The initial size of the metadata partition in number of blocks, default: 32 --userid uid or -U uid Use the specified uid (numeric value only) as the owner of the root directory. --groupid gid or -G gid Use the specified gid (numeric value only) as the group of the root directory.
