I'm not sure how to just move, but OS X will always copy instead of move when it is dealing with two separate hard drive/partitions. Try holding down "ctrl", or "alt", or "command" when dragging the file.

If you're using the iPod in disk mode, it should work. The operating system allows for a move (instead of a copy) across volumes, including network or external volumes.
