Ufsd

From ArchWiki

Ufsd is a closed-source driver for Microsoft's NTFS file system that includes read and write support, developed by Paragon GmbH. It is free for personal use. It offers significantly faster writes to ntfs filesystems than the default ntfs-3g driver. This document will describe how to setup ufsd to work on your computer.

Since 2020-08-14, Paragon has worked to upstream their driver directly into the mainline Linux kernel. Their proprietary driver remains available. See NTFS.

Installation

The ufsd packages uses Dynamic Kernel Module Support so you will not need to bother about rebuilding and reinstalling every time the kernel changes 

$ makepkg -si
  • Check if the module has been installed in dkms.
$ dkms status

Usage

Test using the manual method before setting it up for automatic loading and mounting. Remember to create the target folder before mounting. And, also remember to unmount your ntfs partition if it is already mounted using ntfs-3g.

Manual

# modprobe ufsd
# mount -t ufsd /dev/your-NTFS-partition /{mnt,...}/folder -o uid=your username,gid=users

Automatic

For non-dkms setups, edit /etc/fstab as below: 

# <file system>   <dir>		<type>    <options>             <dump>  <pass>
/dev/NTFS-part  /mnt/windows  ufsd   uid=your username,gid=users,noatime,umask=0222	0 0

For dkms setups, edit /etc/fstab as below: 

# <file system>   <dir>		<type>    <options>             <dump>  <pass>
/dev/NTFS-part  /mnt/windows  ufsd   noauto,x-systemd.automount,uid=your username,gid=users,noatime,umask=0222	0 0

To load the ufsd driver at startup, create a *.conf file (e.g. ufsd.conf) in /etc/modules-load.d/ that contains all modules that should be loaded: 

/etc/modules-load.d/ufsd.conf
ufsd
Note: You may need to update the kernel modules db in order to avoid 'no such file or directory' error when loading ufsd. Run: depmod -a.
