I would like a user without sudo to be able to read and write a subdirectory of an NTFS HDD.

I would like my main user to have read/write access to all the filesystem.

As far as I can tell, I can't change permissions using a bind mount, and I can't directly mount only a subdirectory of an NTFS HDD.

Is there a way to do what I want?

Mounting ntfs subdirectories of device hints at the same problem, but doesn't provide the answer.

With the NTFS-3g driver, mount the filesystem with permission checking enabled – either by using the permissions mount option in fstab, or by creating an UserMapping file.

Then you'll be able to chown each directory to a different user.

  • This works. It appears that if you change permissions on the NTFS mount having mounted like this, they persist across reboots.

  • @wilbo: Yes, they are stored internally as NTFS ACLs, and should be visible from Windows as well (although the translation is imperfect).
