MOUNT_NTFS(8) BSD System Manager's Manual MOUNT_NTFS(8)NAME
mount_ntfs -- mount an NTFS file system
SYNOPSIS
mount_ntfs [-s] [-o options] special node
DESCRIPTION
The mount_ntfs command attaches the NTFS file system residing on the device special to the global file system namespace at the location indi-
cated by node. This command is normally executed by mount(8) at boot time, but can be used by any user to mount an NTFS file system on any
directory that they own (provided, of course, that they have appropriate access to the device that contains the file system).
The options are as follows:
-s Mount the volume using case sensitive semantics. This means that you can create files that have names that only differ in case such
as for example "foo" and "Foo". Without this option the volume is mounted using case insensitive semantics in which case if you cre-
ate a file with name "foo" you then cannot create a file named "Foo" or rather if you do create a file named "Foo" it would overwrite
the existing file "foo".
-o Options are specified with a -o flag followed by a comma separated string of options. See the mount(8) man page for possible options
and their meanings.

MOUNT_NTFS(8) BSD System Manager's Manual MOUNT_NTFS(8)NAME
mount_ntfs -- mount an NTFS file system
SYNOPSIS
mount_ntfs [-a] [-i] [-u uid] [-g gid] [-m mask] special node
DESCRIPTION
The mount_ntfs command attaches the NTFS filesystem residing on the device special to the global filesystem namespace at the location indi-
cated by node. Both special and node are converted to absolute paths before use. This command is normally executed by mount(8) at boot
time, but can be used by any user to mount an NTFS file system on any directory that they own (provided, of course, that they have appropri-
ate access to the device that contains the file system).
The supported NTFS versions include both NTFS4, as used by Microsoft Windows NT 4.0, and NTFS5, as used by Microsoft Windows 2000 and XP.
The options are as follows:
-a Force behaviour to return MS-DOS 8.3 names also on readdir().
-i Make name lookup case insensitive for all names except POSIX names.
-u uid Set the owner of the files in the file system to uid. The default owner is the owner of the directory on which the file system is
being mounted.
-g gid Set the group of the files in the file system to gid. The default group is the group of the directory on which the file system is
being mounted.
-m mask
Specify the maximum file permissions for files in the file system.
FEATURES
NTFS file attributes
NTFS file attributes can be accessed in the following way:
foo[[:ATTRTYPE]:ATTRNAME]
'ATTRTYPE' is one of identifier listed in $AttrDef file of volume. Default is $DATA. 'ATTRNAME' is an attribute name. Default is none.
Examples:
To get volume name (in Unicode):
# cat /mnt/$Volume:$VOLUME_NAME
To read directory raw data:
# cat /mnt/foodir:$INDEX_ROOT:$I30
Limited support for writing
There is limited writing ability for files. Limitations:
o file must be non-resident
o file must not contain any holes (uninitialized areas)
o file can't be compressed
Note that it's not currently possible to create or remove files on NTFS filesystems.
Warning: do not mount NTFS filesystems read-write. The write support is not very useful and is not tested well. It's not safe to write to
any file on NTFS; you might damage the filesystem. Unless you want to debug NTFS filesystem code, mount the NTFS filesystem read-only.

Support for NTFS first appeared in FreeBSD 3.0. It was ported to NetBSD and first appeared in NetBSD 1.5.
AUTHORS
NTFS kernel implementation, mount_ntfs and this manual were originally written by Semen Ustimenko <semenu@FreeBSD.org>.
The NetBSD port was done by
Christos Zoulas <christos@NetBSD.org> and
Jaromir Dolecek <jdolecek@NetBSD.org>.
BUGS
The write support should be enhanced to actually be able to change file size, and to create and remove files and directories. It's not very
useful right now.
If the attempt to mount NTFS gives you an error like this:
# mount -t ntfs /dev/wd0k /mnt
mount_ntfs: /dev/wd0k on /mnt: Invalid argument
make sure that appropriate partition has correct entry in the disk label, particularly that the partition offset is correct. If the NTFS
partition is the first partition on the disk, the offset should be '63' on i386 (see disklabel(8)). mbrlabel(8) could help you to set up the
disk label correctly.
If the NTFS partition is marked as 'dynamic' under Microsoft Windows XP, it won't be possible to access it under NetBSD anymore.
