Arch Linux – Correct Permissions in /etc/fstab to Mount NTFS

arch linuxfstabntfs

I have Windows and Arch Linux in dual with UEFI. I want to mount my another NTFS partition in Arch. I mounted the partition with mount /dev/sda5 /mnt/Apps command. Then added the output of genfstab -U /mnt/Apps in /etc/fstab file. The output is as follows:

UUID=01D158CC7C2A61A0 /mnt/Apps ntfs rw,nosuid,nodev,user_id=0,group_id=0,allow_other 0 0

But when I unmount and remount that partition all files and folders shows with root uid and gid and 0777 permission. I also tried with changing uid and gid to 1000 but same result. So, my question, what is the correct way to add NTFS partitions in fstab so that I can read & write all file and folder both with normal user (1000:1000) and root (0:0)?

As commented by muru from this answer, I have added the fmask and dmask permissions in /etc/fstab and now it shows correct permissions. I have change that line as follows:

UUID=01D158CC7C2A61A0 /mnt/Apps ntfs rw,auto,user,fmask=133,dmask=022,uid=1000,gid=1000 0 0

This sets all files 0644 and directories 0755 permissions.

The ntfs-3g binaries must be set uid root in order for user mounting to work. And you need permission to the block device & mount point.

sudo chmod 1755 /sbin/mount.ntfs-3g /usr/bin/ntfs-3g
sudo chmod 666 /dev/sda2
sudo chmod 777 /media/Windows

(Note: these are the Debian locations, they may differ for Suse, so you will want to check that they are actually in those locations.)

You also need to have ntfs-3g version 1.2506 or later.

You can use \x20 for space.

That is hex value for ASCII (and utf-8 encoded) space.

Or you can use the octal variant \040.

So that would be (in fstab):

UUID=01CD72098BB21B70 /media/tusharmakkar08/Local\x20Disk1
# or
UUID=01CD72098BB21B70 /media/tusharmakkar08/Local\040Disk1

If you are not to familiar with ASCII fun install ascii and:

ascii     # decimal and hex view
ascii -o  # octal view

Non the less I'd also recommend, like @TNW, changing the mount point to one without space. Generally makes things easier. You can also change the label though that might affect other things if you have something configured to recognize it as it is.
