I have mounted an xp ntfs share drive on my raspberri pi with the command sudo mount -t cifs -o guest // /mnt/mtmy

The only way that I can edit and save files in this directory from raspberri pi is to use the sudo command. eg. sudo leafpad etc. Unless I precede with sudo I have a permissions problems and cannot save my changes.

I have tried sudo chmod 666 -r * from the mtmy location and I get "permission denied" response as it recurses. I have also tried sudo chown and got a similar response.

I can access this windows share from other windows machines with no permissions problems so I don't think the problem is related to windows sharing. However, it appears that not even using sudo can make the permissions changes in rpi to grant permission to other users.

  • try chmod 777 -r /mnt/mtmy/ (or 666 or whatever you want) – cutrightjm Jan 2 '15 at 2:06
  • ok, I got thispi@raspberrypi /mnt $ sudo chmod 777 -r /mnt/myny chmod: cannot access 777': No such file or directory chmod: changing permissions of /mnt/myny': Permission denied – user3799318 Jan 2 '15 at 3:45
  • You have the drive mounted already, yes? Also, there's a / on the end of myny/ – cutrightjm Jan 2 '15 at 3:50
  • yes, it is definitely mounted and I just tried adding the "/" on the end and it did not make a difference, same fail message previously posted. As I said, root can add/del/modify files in /mnt/myny/ but a standard user can only open files to view but cannot save or modify. And for whatever reason root cannot do a chmod or chown. – user3799318 Jan 2 '15 at 18:30
  • I have since discovered that this problem is not unique to raspberri pi. I am running debian on a laptop and when I mount that same ntfs network drive only su has rw permission but it does not have authority to run chmod or chown. – user3799318 Jan 2 '15 at 22:14

it is not possible for mounted ntfs permissions to be managed by su. They only can be managed as part of the mount command.
