   1config NTFS_FS
   2        tristate "NTFS file system support"
   3        select NLS
   4        help
   5          NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
   6
   7          Saying Y or M here enables read support.  There is partial, but
   8          safe, write support available.  For write support you must also
   9          say Y to "NTFS write support" below.
  10
  11          There are also a number of user-space tools available, called
  12          ntfsprogs.  These include ntfsundelete and ntfsresize, that work
  13          without NTFS support enabled in the kernel.
  14
  15          This is a rewrite from scratch of Linux NTFS support and replaced
  16          the old NTFS code starting with Linux 2.5.11.  A backport to
  17          the Linux 2.4 kernel series is separately available as a patch
  18          from the project web site.
  19
  20          For more information see <file:Documentation/filesystems/ntfs.txt>
  21          and <http://www.linux-ntfs.org/>.
  22
  23          To compile this file system support as a module, choose M here: the
  24          module will be called ntfs.
  25
  26          If you are not using Windows NT, 2000, XP or 2003 in addition to
  27          Linux on your computer it is safe to say N.
  28
  29config NTFS_DEBUG
  30        bool "NTFS debugging support"
  31        depends on NTFS_FS
  32        help
  33          If you are experiencing any problems with the NTFS file system, say
  34          Y here.  This will result in additional consistency checks to be
  35          performed by the driver as well as additional debugging messages to
  36          be written to the system log.  Note that debugging messages are
  37          disabled by default.  To enable them, supply the option debug_msgs=1
  38          at the kernel command line when booting the kernel or as an option
  39          to insmod when loading the ntfs module.  Once the driver is active,
  40          you can enable debugging messages by doing (as root):
  41          echo 1 > /proc/sys/fs/ntfs-debug
  42          Replacing the "1" with "0" would disable debug messages.
  43
  44          If you leave debugging messages disabled, this results in little
  45          overhead, but enabling debug messages results in very significant
  46          slowdown of the system.
  47
  48          When reporting bugs, please try to have available a full dump of
  49          debugging messages while the misbehaviour was occurring.
  50
  51config NTFS_RW
  52        bool "NTFS write support"
  53        depends on NTFS_FS
  54        help
  55          This enables the partial, but safe, write support in the NTFS driver.
  56
  57          The only supported operation is overwriting existing files, without
  58          changing the file length.  No file or directory creation, deletion or
  59          renaming is possible.  Note only non-resident files can be written to
  60          so you may find that some very small files (<500 bytes or so) cannot
  61          be written to.
  62
  63          While we cannot guarantee that it will not damage any data, we have
  64          so far not received a single report where the driver would have
  65          damaged someones data so we assume it is perfectly safe to use.
  66
  67          Note:  While write support is safe in this version (a rewrite from
  68          scratch of the NTFS support), it should be noted that the old NTFS
  69          write support, included in Linux 2.5.10 and before (since 1997),
  70          is not safe.
  71
  72          This is currently useful with TopologiLinux.  TopologiLinux is run
  73          on top of any DOS/Microsoft Windows system without partitioning your
  74          hard disk.  Unlike other Linux distributions TopologiLinux does not
  75          need its own partition.  For more information see
  76          <http://topologi-linux.sourceforge.net/>
  77
  78          It is perfectly safe to say N here.
