I'm trying to share WD 2TB USB drive connected to a new Raspberry PI.

Running on Raspbian Jessie version 4.1, USB drive mounts automatically. This isn't a problem, but it's not accessible from my Windows 7 computer.

ntfs-3 is already installed and up to date.

I'm not able to change permissions for files on my USB drive:

pi@raspberrypi:/media/pi/WD_2TB/temp $ sudo chmod -v 777 tst2
mode of ‘tst2’ changed from 0600 (rw-------) to 0777 (rwxrwxrwx)
pi@raspberrypi:/media/pi/WD_2TB/temp $ ls -l
total 0
-rw------- 1 pi pi 0 Mar  2 01:34 tst2
pi@raspberrypi:/media/pi/WD_2TB/temp $ 

Just in case, here is part from my smb.conf:

comment = Backup Folder
path = /media/pi/WD_2TB
writeable = Yes
readonly = No
public = Yes
create mask = 0777
directory mask = 0777
browseable = Yes
public = yes
guest = OK
  • What file system is being used? I doubt a Windows formatted disk would recognise Linux permissions.

  • this is NTFS disk. Apparently ntfs-3g should be able to handle it.

NTFS is file system designed by Microsoft that is primarily used by Windows systems. chmod changes the linux permissions on a file. The two are not compatible.

Your cmb.conf file looks correct. My assumption is that you aren't specifying a user/group in the mounting step.

  • Thank you Jacobm001 for quick answer. There is no "mounting/step" on my part. It's automatic.
