NAME
       mkntfs - create an NTFS file system

SYNOPSIS
       mkntfs [options] device [number-of-sectors]

       mkntfs  [  -C ] [ -c cluster-size ] [ -F ] [ -f ] [ -H heads ] [ -h ] [
       -I ] [ -L volume-label ] [ -l ] [ -n ] [ -p part-start-sect ] [ -Q ]  [
       -q ] [ -S sectors-per-track ] [ -s sector-size ] [ -T ] [ -U ] [ -V ] [
       -v ] [ -z mft-zone-multiplier ] [ --debug ] device [  number-of-sectors
       ]

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 zeroing 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 65536 bytes
	      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 disabled 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 sector. 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 a default	 of  0
	      is used. Note that 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 auto‐
	      matically and if that fails a default of 0 is  used.  Note  that
	      heads  is	 required for Windows to be able to boot from the cre‐
	      ated volume.

       -S, --sectors-per-track NUM
	      Specify the number of sectors per track. The  maximum  is	 65535
	      (0xffff). If omitted, mkntfs attempts to determine 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 multi‐
	      plier  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 fragmentation. Valid values
	      are 1, 2, 3 and 4. The values have the following meaning:

	      ┌────────────────────────────────┐
	      │MFT zone	    MFT zone size      │
	      │multiplier   (% of volume size) │
	      │	   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 content 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  warning
       "Correcting  errors  in the uppercase file." The uppercase file is cre‐
       ated while formatting and it defines the mapping of lower case  charac‐
       ters  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 run‐
       ning, and this may happen because newer versions of Windows  take  into
       account new characters defined by the Unicode 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 versions.
