     DESCRIPTION
          mkntfs is used to create an NTFS file system on a device
          (usually a disk partition) or file.  device is the special
          file corresponding to the device (e.g /dev/hdXX).
          number-of-sectors is the number of sectors on the device. If
          omitted, mkntfs automagically figures the file system size.

     OPTIONS
          Below is a summary of all the options that mkntfs accepts.
          Nearly all options have two equivalent names.  The short
          name is preceded by - and the long name is preceded by --.
          Any single letter options, that don't take an argument, can
          be combined into a single command, e.g.  -fv is equivalent
          to -f -v.  Long named options can be abbreviated to any
          unique prefix of their name.

        Basic options
          -f, --fast, -Q, --quick
               Perform quick (fast) format. This will skip both zero-
               ing of the volume and bad sector checking.

          -L, --label STRING
               Set the volume label for the filesystem.

          -C, --enable-compression
               Enable compression on the volume.

          -n, --no-action
               Causes mkntfs to not actually create a filesystem, but
               display what it would do if it were to create a
               filesystem. All steps of the format are carried out
               except the actual writing to the device.

        Advanced options
          -c, --cluster-size BYTES
               Specify the size of clusters in bytes. Valid cluster
               size values are powers of two, with at least 256, and

               at most 2097152 bytes (2MB) per cluster. If omitted,
               mkntfs uses 4096 bytes as the default cluster size.

               Note that the default cluster size is set to be at
               least equal to the sector size as a cluster cannot be
               smaller than a sector. Also, note that values greater
               than 4096 have the side effect that compression is dis-
               abled on the volume (due to limitations in the NTFS
               compression algorithm currently in use by Windows).

          -s, --sector-size BYTES
               Specify the size of sectors in bytes. Valid sector size
               values are 256, 512, 1024, 2048 and 4096 bytes per sec-
               tor. If omitted, mkntfs attempts to determine the
               sector-size automatically and if that fails a default
               of 512 bytes per sector is used.

          -p, --partition-start SECTOR
               Specify the partition start sector. The maximum is
               4294967295 (2^32-1). If omitted, mkntfs attempts to
               determine part-start-sect automatically and if that
               fails or the value is oversized, a default of 0 is
               used. The partition is usable despite a wrong value,
               however note that a correct part-start-sect is required
               for Windows to be able to boot from the created volume.

          -H, --heads NUM
               Specify the number of heads. The maximum is 65535
               (0xffff). If omitted, mkntfs attempts to determine the
               number of heads automatically and if that fails a
               default of 0 is used. Note that heads is required for
               Windows to be able to boot from the created volume.

          -S, --sectors-per-track NUM
               Specify the number of sectors per track. The maximum is
               65535 (0xffff). If omitted, mkntfs attempts to deter-
               mine the number of sectors-per-track automatically and
               if that fails a default of 0 is used. Note that
               sectors-per-track is required for Windows to be able to
               boot from the created volume.

          -z, --mft-zone-multiplier NUM
               Set the MFT zone multiplier, which determines the size
               of the MFT zone to use on the volume. The MFT zone is
               the area at the beginning of the volume reserved for
               the master file table (MFT), which stores the on disk
               inodes (MFT records).  It is noteworthy that small
               files are stored entirely within the inode; thus, if
               you expect to use the volume for storing large numbers
               of very small files, it is useful to set the zone mul-
               tiplier to a higher value. Note, that the MFT zone is
               resized on the fly as required during operation of the

               NTFS driver but choosing a good value will reduce frag-
               mentation. Valid values are 1, 2, 3 and 4. The values
               have the following meaning: box; lB lB lB lB c l.  MFT

               1    12.5% (default) 2    25.0% 3    37.5% 4    50.0%

          -T, --zero-time
               Fake the time to be 00:00:00 UTC, Jan 1, 1970 instead
               of the current system time.  This is only really useful
               for debugging purposes.

          -U, --with-uuid
               Generate a random volume UUID.

          -I, --no-indexing
               Disable content indexing on the volume. (This is only
               meaningful on Windows 2000 and later. Windows NT 4.0
               and earlier ignore this as they do not implement con-
               tent indexing at all.)

          -F, --force
               Force mkntfs to run, even if the specified device is
               not a block special device, or appears to be mounted.

        Output options
          -q, --quiet
               Quiet execution; only errors are written to stderr, no
               output to stdout occurs at all. Useful if mkntfs is run
               in a script.

          -v, --verbose
               Verbose execution.

          --debug
               Really verbose execution; includes the verbose output
               from the -v option as well as additional output useful
               for debugging mkntfs.

        Help options
          -V, --version
               Print the version number of mkntfs and exit.

          -l, --license
               Print the licensing information of mkntfs and exit.

          -h, --help
               Show a list of options with a brief description of each
               one.

     KNOWN ISSUES
          When applying chkdsk to a file system, it sometimes throws a

     MKNTFS(8)                (January 2006)                 MKNTFS(8)

          warning "Correcting errors in the uppercase file." The
          uppercase file is created while formatting and it defines
          the mapping of lower case  characters to upper case ones, as
          needed to sort file names in directories. The warning means
          that the uppercase file defined on the file system is not
          the same as the one used by the Windows OS on which chkdsk
          is running, and this may happen because newer versions of
          Windows take into account new characters defined by the Uni-
          code consortium.

          Currently, mkntfs creates the uppercase table so that no
          warning is thrown by Windows Vista, Windows 7 or Windows 8.
          A warning may be thrown by other Windows versions, or if
          chkdsk is applied in succession on different Windows ver-
          sions.
