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.
- -P discid
-
Set the phyisical disc label to the specified
discid.
For strict conformance and interchange, don't set this manually.
- -S setlabel
-
Set the disc set label to the specified
setlabel.
For strict conformance and interchange, don't set this manually.
- -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.
- -s size
-
Ignored for now.
- -p percentage
-
Percentage of partition to be initially reserved for metadata on the Metadata
partition. It defaults to 20 %.
- -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.
