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 | |||
29 | config 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 | |||
51 | config 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. | ||
