 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.

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.

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.
