NetBSD 6.1.5 - man page for mount_ntfs (netbsd section 8)

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 indicated 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 appropriate 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.

HISTORY
     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 possi-
     ble to access it under NetBSD anymore.
