When I boot up opensuse 11.4 with my externall NTFS drive already plugged into the USB slot, opensuse detects it and mounts it automatically. And I can access its files. But when I plugged in the drive at any other time, the device is detected, but cannot be mounted. I can see the external drive in the Dolphin file explorer, but when I click the device, it displays the error:
Error opening /dev/sdc1: Permission denied
Failed to mount /dev/sdc1: Permission denied
Please check /dev/sdc1 and the ntfs-3g binary permissions
and the mounting user ID.
I searched the internet for advise, but all fails. What do I do next?
Thanks in advance for the help.
