From Windows 10 Creators edition, the cluster size limit has been extended to 2MB. This has implied redefining the boot sector field "sectors_per_cluster" so that values greater than 128 can be recorded.

.SH DESCRIPTION
|
|
.B mkntfs
|
|
is used to create an NTFS file system on a device (usually a disk partition)
|
|
or file.
|
|
.I device
|
|
is the special file corresponding to the device (e.g
|
|
.IR /dev/hdXX ).
|
|
.I number\-of\-sectors
|
|
is the number of sectors on the device. If omitted,
|
|
.B mkntfs
|
|
automagically figures the file system size.
|
|
.SH OPTIONS
|
|
Below is a summary of all the options that
|
|
.B mkntfs
|
|
accepts. Nearly all options have two equivalent names. The short name is
|
|
preceded by
|
|
.B \-
|
|
and the long name is preceded by
|
|
.BR \-\- .
|
|
Any single letter options, that don't take an argument, can be combined into a
|
|
single command, e.g.
|
|
.B \-fv
|
|
is equivalent to
|
|
.BR "\-f \-v" .
|
|
Long named options can be abbreviated to any unique prefix of their name.
|
|
.SS Basic options
|
|
.TP
|
|
\fB\-f\fR, \fB\-\-fast\fR, \fB\-Q\fR, \fB\-\-quick\fR
|
|
Perform quick (fast) format. This will skip both zeroing of the volume and bad
|
|
sector checking.
|
|
.TP
|
|
\fB\-L\fR, \fB\-\-label\fR STRING
|
|
Set the volume label for the filesystem.
|
|
.TP
|
|
\fB\-C\fR, \fB\-\-enable\-compression\fR
|
|
Enable compression on the volume.
|
|
.TP
|
|
\fB\-n\fR, \fB\-\-no\-action\fR
|
|
Causes
|
|
.B 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.
|
|
.SS Advanced options
|
|
.TP
|
|
\fB\-c\fR, \fB\-\-cluster\-size\fR 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,
|
|
.B mkntfs
|
|
uses 4096 bytes as the default cluster size.
|
|
.sp
|
|
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).
|
|
.TP
|
|
\fB\-s\fR, \fB\-\-sector\-size\fR BYTES
|
|
Specify the size of sectors in bytes. Valid sector size values are 256, 512,
|
|
1024, 2048 and 4096 bytes per sector. If omitted,
|
|
.B mkntfs
|
|
attempts to determine the
|
|
.I sector\-size
|
|
automatically and if that fails a default of 512 bytes per sector is used.
|
|
.TP
|
|
\fB\-p\fR, \fB\-\-partition\-start\fR SECTOR
|
|
Specify the partition start sector. The maximum is 4294967295 (2^32\-1). If
|
|
omitted,
|
|
.B mkntfs
|
|
attempts to determine
|
|
.I 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
|
|
.I part\-start\-sect
|
|
is required for Windows to be able to boot from the created volume.
|
|
.TP
|
|
\fB\-H\fR, \fB\-\-heads\fR NUM
|
|
Specify the number of heads. The maximum is 65535 (0xffff). If omitted,
|
|
.B mkntfs
|
|
attempts to determine the number of
|
|
.I heads
|
|
automatically and if that fails a default of 0 is used. Note that
|
|
.I heads
|
|
is required for Windows to be able to boot from the created volume.
|
|
.TP
|
|
\fB\-S\fR, \fB\-\-sectors\-per\-track\fR NUM
|
|
Specify the number of sectors per track. The maximum is 65535 (0xffff). If
|
|
omitted,
|
|
.B mkntfs
|
|
attempts to determine the number of
|
|
.I sectors\-per\-track
|
|
automatically and if that fails a default of 0 is used. Note that
|
|
.I sectors\-per\-track
|
|
is required for Windows to be able to boot from the created volume.
|
|
.TP
|
|
\fB\-z\fR, \fB\-\-mft\-zone\-multiplier\fR 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:
|
|
.TS
|
|
box;
|
|
lB lB
|
|
lB lB
|
|
c l.
|
|

|
1 12.5% (default)

4 50.0%
|
|
.TE
|
|
.sp
|
|
.TP
|
|
\fB\-T\fR, \fB\-\-zero\-time\fR
|
|
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.
|
|
.TP
|
|
\fB\-U\fR, \fB\-\-with\-uuid\fR
|
|
Generate a random volume UUID.
|
|
.TP
|
|
\fB\-I\fR, \fB\-\-no\-indexing\fR
|
|
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.)
|
|
.TP
|
|
\fB\-F\fR, \fB\-\-force\fR
|
|
Force
|
|
.B mkntfs
|
|
to run, even if the specified
|
|
.I device
|
|
is not a block special device, or appears to be mounted.
|
|
.SS Output options
|
|
.TP
|
|
\fB\-q\fR, \fB\-\-quiet\fR
|
|
Quiet execution; only errors are written to stderr, no output to stdout
|
|
occurs at all. Useful if
|
|
.B mkntfs
|
|
is run in a script.
|
|
.TP
|
|
\fB\-v\fR, \fB\-\-verbose\fR
|
|
Verbose execution.
|
|
.TP
|
|
\fB\-\-debug\fR
|
|
Really verbose execution; includes the verbose output from the
|
|
.B \-v
|
|
option as well as additional output useful for debugging
|
|
.B mkntfs.
|
|
.SS Help options
|
|
.TP
|
|
\fB\-V\fR, \fB\-\-version\fR
|
|
Print the version number of
|
|
.B mkntfs
|
|
and exit.
|
|
.TP
|
|
\fB\-l\fR, \fB\-\-license\fR
|
|
Print the licensing information of
|
|
.B mkntfs
|
|
and exit.
|
|
.TP
|
|
\fB\-h\fR, \fB\-\-help\fR
|
|
Show a list of options with a brief description of each one.
|
|
.SH KNOWN ISSUES
|
|
When applying chkdsk to a file system, it sometimes throws a 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 Unicode consortium.
|
|
.P
|
|
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.
