Just a Great Idea!!
it would be great if there was a way I can use TuneSpan to use as a backup for the spanned location. Example: I have one external hard drive tied to iTunes but then that hard drive crashes and I've lost all of my stuff. If there was an EASY way to use TuneSpan to backup the info on first external hard drive to another external hard drive, then this would be easy to move beyond a broken hard drive very easy.
