NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
|
|
|
|
Saying Y or M here enables read support. There is partial, but
|
|
safe, write support available. For write support you must also
|
|
say Y to "NTFS write support" below.
|
|
|
|
There are also a number of user-space tools available, called
|
|
ntfsprogs. These include ntfsundelete and ntfsresize, that work
|
|
without NTFS support enabled in the kernel.
|
|
|
|
This is a rewrite from scratch of Linux NTFS support and replaced
|
|
the old NTFS code starting with Linux 2.5.11. A backport to
|
|
the Linux 2.4 kernel series is separately available as a patch
|
|
from the project web site.
|
|
|
|
For more information see <file:Documentation/filesystems/ntfs.txt>
|
|
and <http://www.linux-ntfs.org/>.
|
|
|
|
To compile this file system support as a module, choose M here: the
|
|
module will be called ntfs.
|
|
|
|
If you are not using Windows NT, 2000, XP or 2003 in addition to
|
|
Linux on your computer it is safe to say N.

|
help
|
|
If you are experiencing any problems with the NTFS file system, say
|
|
Y here. This will result in additional consistency checks to be
|
|
performed by the driver as well as additional debugging messages to
|
|
be written to the system log. Note that debugging messages are
|
|
disabled by default. To enable them, supply the option debug_msgs=1
|
|
at the kernel command line when booting the kernel or as an option
|
|
to insmod when loading the ntfs module. Once the driver is active,
|
|
you can enable debugging messages by doing (as root):
|
|
echo 1 > /proc/sys/fs/ntfs-debug
|
|
Replacing the "1" with "0" would disable debug messages.
|
|
|
|
If you leave debugging messages disabled, this results in little
|
|
overhead, but enabling debug messages results in very significant
|
|
slowdown of the system.
|
|
|
|
When reporting bugs, please try to have available a full dump of
|
|
debugging messages while the misbehaviour was occurring.

|
|
This enables the partial, but safe, write support in the NTFS driver.
|
|
|
|
The only supported operation is overwriting existing files, without
|
|
changing the file length. No file or directory creation, deletion or
|
|
renaming is possible. Note only non-resident files can be written to
|
|
so you may find that some very small files (<500 bytes or so) cannot
|
|
be written to.
|
|
|
|
While we cannot guarantee that it will not damage any data, we have
|
|
so far not received a single report where the driver would have
|
|
damaged someones data so we assume it is perfectly safe to use.
|
|
|
|
Note: While write support is safe in this version (a rewrite from
|
|
scratch of the NTFS support), it should be noted that the old NTFS
|
|
write support, included in Linux 2.5.10 and before (since 1997),
|
|
is not safe.
|

|
This is currently useful with TopologiLinux. TopologiLinux is run
|
|
on top of any DOS/Microsoft Windows system without partitioning your
|
|
hard disk. Unlike other Linux distributions TopologiLinux does not
|
|
need its own partition. For more information see
|
|
<http://topologi-linux.sourceforge.net/>
|
|
|
|
It is perfectly safe to say N here.
