I wanted to modify my mount options for my NTFS external HDD so that I can execute programs on it. I added the following line to my fstab accordingly:

UUID=CE665A3F665A290B  /media/Josh  ntfs-3g defaults,users,nofail 0 0

But when I plug in my external and I get this error:

Error mounting: mount exited with exit code 1: helper failed with:
Error opening '/dev/sdb1': Permission denied
Failed to mount '/dev/sdb1': Permission denied
Please check '/dev/sdb1' and the ntfs-3g binary permissions, and the mounting user ID. More explanation is provided at http://tuxera.com/community/ntfs-3g-faq/#unprivileged.

Soo I go to the URL provided. It says:

Unprivileged block device mounts work only if all the below requirements are met:

  1. ntfs-3g is compiled with integrated FUSE support
  2. the ntfs-3g binary is at least version 1.2506
  3. the ntfs-3g binary is set to setuid-root
  4. the user has access right to the volume
  5. the user has access right to the mount point

I believe I have all 5 requirements met (though obviously not, since I'm getting that error). Anyone have some tips? In particular, I have:

  1. ntfs-3g 2014.2.15 integrated FUSE 27
  2. ntfs-3g 2014.2.15 integrated FUSE 27
  3. -rwsr-xr-x 1 root root 504887 Mar 8 12:06 /bin/ntfs-3g*
  4. brw-rw---- 1 root disk 8, 17 Mar 8 16:43 /dev/sdb1 (my user is in the "disk" group)
  5. drwxrwxrwx 2 josh josh 4096 Mar 8 12:42 Josh/

Been struggling with this for hours. This link has been the most helpful so far, but notably the last post has my same question and is unanswered.

Thanks!

Found an answer that lets me not edit my fstab to get what I want. Since my disk gets automounted, I added a rule to my udev that told the automount to do something special upon plug-in (that I don't really understand). But now my disk gets automounted with all files executable. I created a file /etc/udev/rules.d/99-usb-disks.rules and added:

ENV{ID_FS_TYPE}=="ntfs", ENV{ID_FS_TYPE}="ntfs-3g"

Still haven't found a way to get rid of my permissions error when I do use my fstab mod, though.

Thanks terdon for the help.
