NEWFS_UDF(8) BSD System Manager's Manual NEWFS_UDF(8)NAMEnewfs_udf — construct a new UDF file system
SYNOPSISnewfs_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 suit‐
able 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.
EXAMPLESnewfs_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.
