 NTFS3
 =====

 Summary and Features
 ====================
 
-NTFS3 is fully functional NTFS Read-Write driver. The driver works with
-NTFS versions up to 3.1, normal/compressed/sparse files
-and journal replaying. File system type to use on mount is 'ntfs3'.
+NTFS3 is fully functional NTFS Read-Write driver. The driver works with NTFS
+versions up to 3.1. File system type to use on mount is *ntfs3*.
 
 - This driver implements NTFS read/write support for normal, sparse and
   compressed files.
-- Supports native journal replaying;
-- Supports extended attributes
-	Predefined extended attributes:
-	- 'system.ntfs_security' gets/sets security
-			descriptor (SECURITY_DESCRIPTOR_RELATIVE)
-	- 'system.ntfs_attrib' gets/sets ntfs file/dir attributes.
-		Note: applied to empty files, this allows to switch type between
-		sparse(0x200), compressed(0x800) and normal;
+- Supports native journal replaying.
 - Supports NFS export of mounted NTFS volumes.
+- Supports extended attributes. Predefined extended attributes:
+
+	- *system.ntfs_security* gets/sets security
+
+		Descriptor: SECURITY_DESCRIPTOR_RELATIVE
+
+	- *system.ntfs_attrib* gets/sets ntfs file/dir attributes.
+
+	  Note: Applied to empty files, this allows to switch type between
+	  sparse(0x200), compressed(0x800) and normal.
 
 Mount Options
 =============
 
 The list below describes mount options supported by NTFS3 driver in addition to
-generic ones.
+generic ones. You can use every mount option with **no** option. If it is in
+this table marked with no it means default is without **no**.
 
-===============================================================================
+.. flat-table::
+   :widths: 1 5
+   :fill-cells:
 
-nls=name		This option informs the driver how to interpret path
-			strings and translate them to Unicode and back. If
-			this option is not set, the default codepage will be
-			used (CONFIG_NLS_DEFAULT).
-			Examples:
-				'nls=utf8'
+   * - iocharset=name
+     - This option informs the driver how to interpret path strings and
+       translate them to Unicode and back. If this option is not set, the
+       default codepage will be used (CONFIG_NLS_DEFAULT).
 
-uid=
-gid=
-umask=			Controls the default permissions for files/directories created
-			after the NTFS volume is mounted.
+       Example: iocharset=utf8
 
-fmask=
-dmask=			Instead of specifying umask which applies both to
-			files and directories, fmask applies only to files and
-			dmask only to directories.
+   * - uid=
+     - :rspan:`1`
+   * - gid=
 
-nohidden		Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN)
-			attribute will not be shown under Linux.
+   * - umask=
+     - Controls the default permissions for files/directories created after
+       the NTFS volume is mounted.
 
-sys_immutable		Files with the Windows-specific SYSTEM
-			(FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system
-			immutable files.
+   * - dmask=
+     - :rspan:`1` Instead of specifying umask which applies both to files and
+       directories, fmask applies only to files and dmask only to directories.
+   * - fmask=
 
-discard			Enable support of the TRIM command for improved performance
-			on delete operations, which is recommended for use with the
-			solid-state drives (SSD).
+   * - noacsrules
+     - "No access rules" mount option sets access rights for files/folders to
+       777 and owner/group to root. This mount option absorbs all other
+       permissions.
 
-force			Forces the driver to mount partitions even if 'dirty' flag
-			(volume dirty) is set. Not recommended for use.
+       - Permissions change for files/folders will be reported as successful,
+	 but they will remain 777.
 
-sparse			Create new files as "sparse".
+       - Owner/group change will be reported as successful, butthey will stay
+	 as root.
 
-showmeta		Use this parameter to show all meta-files (System Files) on
-			a mounted NTFS partition.
-			By default, all meta-files are hidden.
+   * - nohidden
+     - Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute
+       will not be shown under Linux.
 
-prealloc		Preallocate space for files excessively when file size is
-			increasing on writes. Decreases fragmentation in case of
-			parallel write operations to different files.
+   * - sys_immutable
+     - Files with the Windows-specific SYSTEM (FILE_ATTRIBUTE_SYSTEM) attribute
+       will be marked as system immutable files.
 
-no_acs_rules		"No access rules" mount option sets access rights for
-			files/folders to 777 and owner/group to root. This mount
-			option absorbs all other permissions:
-			- permissions change for files/folders will be reported
-				as successful, but they will remain 777;
-			- owner/group change will be reported as successful, but
-				they will stay as root
+   * - discard
+     - Enable support of the TRIM command for improved performance on delete
+       operations, which is recommended for use with the solid-state drives
+       (SSD).
 
-acl			Support POSIX ACLs (Access Control Lists). Effective if
-			supported by Kernel. Not to be confused with NTFS ACLs.
-			The option specified as acl enables support for POSIX ACLs.
+   * - force
+     - Forces the driver to mount partitions even if volume is marked dirty.
+       Not recommended for use.
 
-noatime			All files and directories will not update their last access
-			time attribute if a partition is mounted with this parameter.
-			This option can speed up file system operation.
+   * - sparse
+     - Create new files as sparse.
 
-===============================================================================
+   * - showmeta
+     - Use this parameter to show all meta-files (System Files) on a mounted
+       NTFS partition. By default, all meta-files are hidden.
 
-ToDo list
-=========
+   * - prealloc
+     - Preallocate space for files excessively when file size is increasing on
+       writes. Decreases fragmentation in case of parallel write operations to
+       different files.
 
-- Full journaling support (currently journal replaying is supported) over JBD.
+   * - acl
+     - Support POSIX ACLs (Access Control Lists). Effective if supported by
+       Kernel. Not to be confused with NTFS ACLs. The option specified as acl
+       enables support for POSIX ACLs.
 
+Todo list
+=========
+- Full journaling support over JBD. Currently journal replaying is supported
+  which is not necessarily as effectice as JBD would be.
