I know there has been a lot of threads about this issue and most have been cleared up but not mine. I am a newbie and the terminal commands must be over my head. I tried to use pysdm but when it loads, it shows the drives on left window but everything on the right side is faded grey and no changes can be made. I had loaded pysdm via the software manager and then uninstalled and did the install via the terminal but same results.
So can someone walk a dummy like me through how to fix the permission issues on external USB drives, Internal Mounted Hard Drives and then on how to get Pysdm to work correctly?
