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 format‐
ting 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 effi‐
ciently 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
implementations.
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., back‐
ground 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.
