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 blocks 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 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 determine
the number of sectors-per-track automatically and if that fails a default of 0 is used. Note that sec-
tors-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 multiplier 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.
