Well the Sansa is no iPod killer, but nonetheless, I picked one up for just a hundred bucks. However in trying to get it to show up on the Mac Desktop upon connection, I have had luck only once. I switched the unit to MSC mode so that it would show up as a flash drive on my desktop (like it should), but no luck - worked only one time. I have tried plugging and unplugging it, switching USB modes, etc., nothing - NADA. Anyone know of a work around? Perhaps I can delete a preference to refresh the recognition of the device?? Any help would be appreciated.
