 | 887 | 	  performed by the driver as well as additional debugging messages to | 
 | 888 | 	  be written to the system log.  Note that debugging messages are | 
 | 889 | 	  disabled by default.  To enable them, supply the option debug_msgs=1 | 
 | 890 | 	  at the kernel command line when booting the kernel or as an option | 
 | 891 | 	  to insmod when loading the ntfs module.  Once the driver is active, | 
 | 892 | 	  you can enable debugging messages by doing (as root): | 
 | 893 | 	  echo 1 > /proc/sys/fs/ntfs-debug | 
 | 894 | 	  Replacing the "1" with "0" would disable debug messages. |

 | 909 | 	  The only supported operation is overwriting existing files, without | 
 | 910 | 	  changing the file length.  No file or directory creation, deletion or | 
 | 911 | 	  renaming is possible.  Note only non-resident files can be written to | 
 | 912 | 	  so you may find that some very small files (<500 bytes or so) cannot | 
 | 913 | 	  be written to. | 
 | 914 |  | 
 | 915 | 	  While we cannot guarantee that it will not damage any data, we have | 
 | 916 | 	  so far not received a single report where the driver would have | 
 | 917 | 	  damaged someones data so we assume it is perfectly safe to use. | 
 | 918 |  | 
 | 919 | 	  Note:  While write support is safe in this version (a rewrite from | 
 | 920 | 	  scratch of the NTFS support), it should be noted that the old NTFS | 
 | 921 | 	  write support, included in Linux 2.5.10 and before (since 1997), | 
 | 922 | 	  is not safe. | 
 | 923 |  |

 | 925 | 	  on top of any DOS/Microsoft Windows system without partitioning your |
