NEWFS_UDF(8)                System Manager's Manual               NEWFS_UDF(8)

     newfs_udf -- construct a new UDF file system

     newfs_udf [-cFM] [-B blockingsize] [-L loglabel] [-P discid]
               [-p percentage] [-S sectorsize] [-s size] [-t gmtoff]
               [-V max_udf] [-v min_udf] special

     The newfs_udf utility creates an UDF file system on device special
     suitable for the media currently inserted.

     The options are as follow:

     -B blockingsize
             When creating image files, specify the blocking size or
             packetsize of the media to blockingsize.

     -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 or
             create an image file.

     -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.

             Prepend discid with volsetname separated with a ':' if wanted.
             For strict conformance and interchange, don't set this manually
             unless it has a unique hex number in the first 8 character

     -p percentage
             Percentage of partition to be initially reserved for metadata on
             the Metadata partition.  It defaults to 20 %.

     -S sectorsize
             Set the sectorsize for image files.  For strict conformance and
             interchange, don't set this manually.

     -s size
             For image files, set the file size to the humanized size size.

     -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''.

     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.

     Create a file system, using the specified names on the device /dev/rcd0d
     with the default UDF version :

           newfs_udf -P "Encyclopedia:copy-nr-1" -L "volume 2" /dev/rcd0d

     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 :

           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 2 GiB file and create a new UDF file system on it using the
     default 512 byte sector size :

           newfs_udf -L bigdisk2 -F -s 2G bigdisk2.iso

     Create a 200 MiB file and create a new UDF file system on it using a
     sector size of 2048 :

           newfs_udf -L bigdisk2 -F -s 200M -S 2048 bigdisk3.iso

     Create a new UDF file system on the inserted USB stick using its native
     sectorsize of 512 :

           newfs_udf -L "My USB stick" /dev/rsd0d

     disktab(5), disklabel(8), mmcformat(8), newfs(8)

     The newfs_udf command first appeared in NetBSD 5.0.

     The P and the S arguments have changed meaning.  The meaning of S has
     been merged into P since NetBSD 6.1.
