I have a separate hard drive where my games and steam files are stored that I use on Windows. When I try to install games to that hard drive using steam I get an error that says “new steam library folder must be on a filesystem mounted with execute permissions”. After searching for solutions, I tried to find a way to change the permissions of the drive and what I know is that you can’t change the permissions on a NTFS filesystem so I edited my fstab file and added "permissions" on the line for my drive and I have tried to edit the permissions by opening a file system as root, right clicking and selecting properties but every time I change it, it just goes back to root. On properties it says the owner is root with read & write access and the group is also root. I have another drive shared by windows where most of my files are stored which I use with both windows and Ubuntu and there are no permission problems with that drive. When I select properties from that drive it says my username with read & write access with the group root.

This is what is says in fstab for my 2 drives. The top one is the windows hard drive that works fine and the bottom one is the drive I’m trying to change the permissions of.

/dev/disk/by-uuid/8482DBD682DBCB36 /mnt/windows auto nosuid,nodev,nofail,x-gvfs-show,remove_hiberfile,uid=1000 0 0

/dev/disk/by-uuid/DC9C1F849C1F587A /mnt/DC9C1F849C1F587A ntfs-3g nosuid,nodev,nofail,x-gvfs-show,permissions,umask=002 0 0

This is the Windows drive with my normal files with the right permissions

And this is the 1tb drive that I install my games on that I can't change the permissions of.

  • check the permissions on the folder that you are mounting to – ravery Jun 27 '17 at 17:52
  • The owner is root and the group is root – user705051 Jul 3 '17 at 12:30
  • is that the same as the other folder? I think you need to have write permission on the folder it mounts to – ravery Jul 3 '17 at 12:37
  • The other folder's owner is my username – user705051 Jul 3 '17 at 12:47
  • make yourself owner of the this folder also – ravery Jul 3 '17 at 12:49

A possible cause of read-only NTFS partition could be the Fast Startup turned on in Windows (8 and 10 version).

See this article to learn what it is (basically, a hybernation variation), and how to disable it.

  • I logged into Windows and changed the setting but it still can't change the permissions. – user705051 Jun 29 '17 at 11:00
  • Mine is very simple in fstab: UUID=FC34798E34794CA0 /home/thunder/DiskD ntfs-3g permissions 0 1 – Aurel Branzeanu Jun 30 '17 at 1:37
