First i had the base-dir owned by root.root (non-writeable), next i made it writeable and verified that its correctly detected as such. Next i created a "Music" folder and configured it for this USB-Stick. I checked that it was detected as writeable. Next i made the "Music" folder non-writeable and checked that amarok also detected that.
