NTFS

From Wikipedia:

NTFS (New Technology File System) is a proprietary journaling file system developed by Microsoft. Starting with Windows NT 3.1, it is the default file system of the Windows NT family.

The ntfs3 kernel driver provides read and write support for the file system.

Note:

All officially supported kernels with versions 5.15 or newer are built with CONFIG_NTFS3_FS=m and thus support it. Before 5.15, NTFS read and write support is provided by the NTFS-3G FUSE file system. Or you can use backported NTFS3 via ntfs3-dkms^AUR.
Paragon Software, the author of the kernel module, has not yet released userspace utilities for NTFS3. You can use NTFS-3G userspace utilities without NTFS-3G driver via ntfsprogs-ntfs3^AUR.

Tips and tricks

Improving performance

You can enable the prealloc mount(8) option to decrease fragmentation in case of parallel write operations (most useful for HDD).

Prevent creation of names not allowed by Windows

NTFS itself does not have restrictions for characters and names used, but Windows does.

Since the kernel version 6.2, ntfs3 supports windows_names mount(8) option. Use it to strictly maintain compatibility.

Note: udisks has this option enabled by default.

Known issues

Explicit file system type required to mount

ntfs3 requires the file system type to mount.

To be able to mount the file system, specify its type as ntfs3. For example, using mount(8)'s -t/--types option:

# mount -t ntfs3 /dev/sdxY /mnt

Troubleshooting

unknown filesystem type 'ntfs'

When mounting NTFS, you can encounter an error such as:

mount: /mnt: unknown filesystem type 'ntfs'

See #Explicit file system type required to mount.

If you want to use ntfs3 as the default driver for ntfs partitions, such udev rule does the trick:

/etc/udev/rules.d/ntfs3_by_default.rules

SUBSYSTEM=="block", ENV{ID_FS_TYPE}=="ntfs", ENV{ID_FS_TYPE}="ntfs3"

Although, this method is not recommended and can confuse some 3rd party tools.

udisks support

This article or section is out of date.

Reason: The described problems have been fixed. Since kernel version 6.2, ntfs3 supports windows_names option. (Discuss in Talk:NTFS)

udisks supports NTFS3, but has some issues at the moment. See udisks ntfs3 PR and issue 932.

Issues can manifest as the following errors, when the NTFS3 driver is used because NTFS-3G is not installed, but with mount options that it does not recognize:

ntfs3: Unknown parameter 'windows_names'

or

Filesystem type ntfs3,ntfs not configured in kernel

The second error in particular can be encountered with Dolphin. Nautilus can also report the same error message in the case of a dirty NTFS partition (see #Unable to mount with ntfs3 with partition marked dirty).

As a workaround, add a such option to /etc/udisks2/mount_options.conf in [defaults] section:

ntfs_defaults=uid=$UID,gid=$GID,prealloc

See: Cannot mount NTFS with the new ntfs3 module from Linux 5.15

Unable to mount with ntfs3 with partition marked dirty

When trying to mount a good NTFS partition (i.e. which successfully mounts with NTFS-3G and for which ntfsfix --no-action does not report any error), you may get the following error:

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

ntfs3 will not mount a partition where the volume is marked dirty without the force option. dmesg explicitly helps recognizing the situation, saying:

sdb1: volume is dirty and "force" flag is not set!

You can try passing the --clear-dirty argument to ntfsfix to clean it. [1]
