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

NAME
     newfs_udf -- construct a new UDF file system

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

DESCRIPTION
     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
             positions.

     -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''.

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
     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

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