.SH OPTIONS
.TP
-.BI \-b " block-size"
-Specify the size of blocks in bytes. Valid block size vales are 1024,
-2048 and 4096 bytes per block. If omitted,
-.B mkntfs
-block-size is determined by the file system size and the expected usage
-of the filesystem (see the
-.B \-T
-option).
+.BI \-s " sector-size"
+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
+.I sector-size
+is determined automatically and if that fails a default of 512
+bytes per sector is used.
+.TP
+.BI \-c " cluster-size"
+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,
+.B mkntfs
+.I cluster-size
+is determined by the volume size. The value is determined as
+follows:
+.br
+.B \tVolume size\tDefault cluster size (in bytes)
+.br
+ \<= 512MB 512
+.br
+ \]512MB-1GB\] 1024
+.br
+ \]1GB-2GB\] 2048
+.br
+ \> 2GB 4096
+.br
+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
-.B \-c
-Check the device for bad blocks before creating the file system, using a
-fast read-only test.
+.BI \-L " volume-label"
+Set the volume label for the filesystem.
+.TP
+.BI \-z " mft-zone-multiplier"
+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:
+.br
+.B \tMFT zone\t\tMFT zone size
+.br
+.B \tmultiplier\t(in % of volume size)
+.br
+ 1 12.5% (default)
+.br
+ 2 25%
+.br
+ 3 37.5%
+.br
+ 4 50%
.TP
-.BI \-f " fragment-size"
-Specify the size of fragments in bytes.
+.B \-f
+Same as
+.BR \-Q .
.TP
-.BI \-i " bytes-per-inode"
-Specify the bytes/inode ratio.
-.B mkntfs
-creates an inode for every
-.I bytes-per-inode
-bytes of space on the disk.
-The larger the
-.I bytes-per-inode
-ratio, the fewer inodes will be created.
-This value generally shouldn't be smaller than
-the blocksize of the filesystem, since then too many inodes will be made.
-Be warned that is not possible to expand the number of inodes on a
-filesystem after it is created, so be careful decided the correct
-value for this parameter.
+.B \-Q
+Perform quick format. This will skip both zeroing of the volume and bad sector
+checking.
.TP
.B \-n
-causes mkntfs to not actually create a filesystem, but display what it
-would do if it were to create a filesystem.
-.TP
-.BI \-N " number-of-inodes"
-overrides the default calculation of the number of inodes that should be
-reserved for the filesystem (which is based on the number of blocks and
-the
-.I bytes-per-inode
-ratio). This allows the user to specify the number
-of desired inodes directly.
-.TP
-.BI \-O " feature\fR[,...]"
-Create the filesystem with the listed set of features
-(filesystem options). The following features are supported:
-.IR sparse_super ,
-which cause the filesystem to use sparse superblocks, and
-.IR filetype ,
-which will cause the filesystem to store file type information in
-directory entries. Currently, both features are turned on by default
-unless
-.B mkntfs
-is run on a system with a pre-2.2 Linux kernel.
-.B Warning:
-Pre-2.2 Linux kernels do not properly
-support the filesystems that use either of these two features. Filesystems
-that may need to mounted on pre-2.2 kernels should be created with
-.B -O
-.I none
-which will disable both of these features, even if
-.B mkntfs
-is run on a system which can support these features.
-.TP
-.BI \-l " filename"
-Read the bad blocks list from
-.I filename.
-\.
-.TP
-.BI -m " reserved-blocks-percentage"
-Specify the percentage of reserved blocks for the super-user. This value
-defaults to 5%.
-.\" .TP

-Set the volume label for the filesystem.
-.TP
-.B \-M
-Set the last mounted directory for the filesystem. This might be useful
-for the sake of utilities that key off of the last mounted directory to
-determine where the filesytem should be mounted.
-.TP
-.BI -r " revision"
-Set the filesystem revision for the new filesystem. Note that 1.2
-kernels only support revision 0 filesystems.
-.TP
-.BI \-R " raid_options"
-Set raid-related options for the filesystem. Raid options are comma
-separated, and may take an argument using the equals ('=') sign.
-Currently the only supported argument is
-.I stride
-which takes as its argument the number of blocks in a RAID stripe.
-.TP
-.B \-S
-Write superblock and group descriptors only. This is useful if all of
-the superblock and backup superblocks are corrupted, and a last-ditch
-recovery method is desired. It causes
-.B mkntfs
-to reinitialize the
-superblock and group descriptors, while not touching the inode table
-and the block and inode bitmaps. The

-program should be run immediately after this option is used, and there
-is no guarantee that any data will be salvageable.

.B mkntfs
-writes the backup boot sector to the last sector of the block device. However,
-current versions of the Linux kernel (all versions up to today's 2.4.5) only
-report an even number of sectors when the sector size is below 1024 bytes,

+.I device
+\. However, current versions of the Linux kernel (all versions up to and
+including todays 2.4.5) only report an even number of sectors when the sector
+size is below 1024 bytes,
which is the case for most hard drives today (512 bytes sector size). This
means that when a partition has an odd number of 512-byte sectors, the last
sector is not reported to us and hence the created NTFS volume will have the
backup boot sector placed one sector ahead of where it should be. For this
-reason, mkntfs marks the NTFS volume dirty so that when you reboot into
-Windows, check disk runs automatically and creates a copy of the backup boot
-sector in the correct location. This also has the benefit of catching any bugs
-in mkntfs as check disk would find any corrupt on disk structures and repair
-them as well as report them. - If you do see any problems reported, please
-report the messages to the author (see below). Thank you.
