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
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 over-write), overwrite),
write), default: ow
-o Keep the disc as open by only writing the first AVDP (e.g., background formating haven't fin-ish, finish,
ish, 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, ecc-SizeInBlks, eccSizeInBlks,
SizeInBlks, packetSize)
--meta-part-align-unit n
The alignment unit size of the metadata partition in number of blocks, default: max(eccSizeIn-Blks, max(eccSizeInBlks,
Blks, packetSize)
--meta-part-init-size n
The initial size of the metadata partition in number of blocks, default: 32
