removing stub for special handling of 'sd' prefix in file paths from knob

passing a path with an 'sd' prefix will now act like any other path on the first drive, instead of closing the calling program.
eventually, i will add a system of mounting drives directly into a file hierarchy (like in unix), and have all of the system calls just pass a path, no drive number
