newfs_udf -- construct a new UDF file system SYNOPSIS
newfs_udf [-cFM] [-L loglabel] [-P discid] [-p percentage] [-S setlabel] [-s size] [-t gmtoff] [-V max_udf] [-v min_udf] special DESCRIPTION
The newfs_udf utility creates an UDF file system on device special suitable for the media currently inserted. The options are as follow: -c Perform a crude surface check first to weed out disc faults on rewritable media. -F Force file system construction on non-empty recordable media. -L loglabel Set the disc logical label to the specified loglabel. -M Disable metadata partition creation when selected UDF version or media dictates this. For strict conformance and interchange, don't disable this unless its causing problems. -P discid Set the physical disc label to the specified discid. For strict conformance and interchange, don't set this manually. -p percentage Percentage of partition to be initially reserved for metadata on the Metadata partition. It defaults to 20 %. -S setlabel Set the disc set label to the specified setlabel. For strict conformance and interchange, don't set this manually. -s size Ignored for now. -t gmtoff Use the specified gmtoff as gmt time offset for recording times on the disc. -V max_udf Select max_udf as the maximum UDF version to be supported. For UDF version 2.50, use ``0x250'' or ``2.50''. -v min_udf Select min_udf as the minimum UDF version to be supported. For UDF version 2.01, use ``0x201'' or ``2.01''. NOTES
The UDF file system is defined for the entire optical medium. It can only function on the entire CD/DVD/BD so the raw partition has to be specified for read/write actions. For newfs_udf this means specifying the raw device with the raw partition, i.e. /dev/rcd0d or /dev/rcd0c. Some rewritable optical media needs to be formatted first before it can be used by UDF. This can be done using mmcformat(8). The default UDF version is version 2.01. EXAMPLES
newfs_udf -S "Encyclopedia" -L "volume 2" -P "copy-nr-1" /dev/rcd0d Create a file system, using the specified names on the device /dev/rcd0d with the default UDF version. dd if=/dev/zero of=bigdisk.2048.udf seek=9999999 count=1 vnconfig -c vnd0 bigdisk.2048.udf 2048/1/1/1 newfs_udf -L bigdisk /dev/rvnd0d Create a 4.8 GiB sparse file and configure it using vnconfig(8) to be a 2048 sector size disc and create a new UDF file system on /dev/rvnd0d. newfs_udf -L "My USB stick" /dev/rsd0d Create a new UDF file system on the inserted USB stick using its ``native'' sectorsize of 512.

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.
