^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) There are also a number of user-space tools available, called

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) If you are experiencing any problems with the NTFS file system, say
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) Y here. This will result in additional consistency checks to be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) performed by the driver as well as additional debugging messages to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) be written to the system log. Note that debugging messages are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) disabled by default. To enable them, supply the option debug_msgs=1
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) at the kernel command line when booting the kernel or as an option
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) to insmod when loading the ntfs module. Once the driver is active,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) you can enable debugging messages by doing (as root):
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) echo 1 > /proc/sys/fs/ntfs-debug
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) Replacing the "1" with "0" would disable debug messages.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) If you leave debugging messages disabled, this results in little
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) overhead, but enabling debug messages results in very significant
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) slowdown of the system.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) When reporting bugs, please try to have available a full dump of

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61) so you may find that some very small files (<500 bytes or so) cannot

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 69) scratch of the NTFS support), it should be noted that the old NTFS
