welp, this is what I have done. After I had the bulk of my music ripped on the computer, I reformated the clip, and scrolled halfway down in my library (I am using windows media player). It looked like between k and l was halfway for me so I have a-k on the internal drive, and l to z on the external. This makes it easy to set up identical mulitple devices.
When I add something, I know where it needs to go on the clip by the name.
Oh, I take it off auto and pick a usb mode that is not auto.
