Unless I am sorely mistaken, you are only allowed one entry in fstab per device. Otherwise, you create a conflict of some kind. Even if thay seem to be one and the same. Your fstab has 2 entries for the same device. Try commenting out 1 of the lines (add the # before the line) and see if that works. If it does not, remove that # and add it to the next line. Then try again.
If both of those fail, try editing fstab. Change owner to user, so that the logged-in user has permission to mount. You could also try changing owner to users, so that members of the users group have permission.
