+== Using NTFS Disks
+
+This section explains how to mount NTFS disks in FreeBSD.
+
+NTFS (New Technology File System) is a proprietary journaling file system
+developed by Microsoft(R).  It has been the default file system in Microsoft
+Windows(R) for many years.  FreeBSD can mount NTFS volumes using a FUSE file
+system.  These file systems are implemented as user space programs which
+interact with the man:fusefs[5] kernel module via a well defined interface.
+
+[.procedure]
+====
+*Procedure: Steps to Mount a NTFS Disk*
+
+. Before using a FUSE file system we need to load the man:fusefs[5] kernel
+module:
++
+[source,bash]
+....
+# kldload fusefs
+....
++
+Use man:sysrc[8] to load the module at startup:
++
+[source,bash]
+....
+# sysrc kld_list+=fusefs
+....
+
+. Install the actual NTFS file system from packages as in the example (see
+crossref:ports[pkgng-intro,Using pkg for Binary Package Management]) or from
+ports (see crossref:ports[ports-using,Using the Ports Collection]):
++
+[source,bash]
+....
+# pkg install fusefs-ntfs
+....
+
+. Last we need to create a directory where the file system will be mounted:
++
+[source,bash]
+....
+# mkdir /mnt/usb
+....
+
+. Suppose a USB disk is plugged in.  The disk partition information can be
+viewed with man:gpart[8]:
++
+[source,bash]
+....
+# gpart show da0
+=>	  63  1953525105  da0 MBR   (932G)
+	  63  1953525105    1 ntfs  (932G)
+....
+
+. We can mount the disk using the following command:
++
+[source,bash]
+....
+# ntfs-3g /dev/da0s1 /mnt/usb/
+....
+The disk is now ready to use.
++
+. Additionally, an entry can be added to /etc/fstab:
++
+[.programlisting]
+....
+/dev/da0s1  /mnt/usb	ntfs mountprog=/usr/local/bin/ntfs-3g,noauto,rw  0 0
+....
++
+Now the disk can be now mounted with:
++
+[source,bash]
+....
+# mount /mnt/usb
+....
+
+. The disk can be unmounted with:
++
+[source,bash]
+....
+# umount /mnt/usb/
+....
