I'm not sure that will help, since I don't think the goal is to add the device tracks to the regular library.
@RetroGameReaper, are you trying to edit the track tags or just add/remove tracks? If the former, I'd suggest making the changes in your library and then re-syncing. Even with the great wifi sync app, I don't think tag changes get synced back.
In any case, I don't think you need to worry too much about that message. That happens to me with my NAS occasionally, which I think has to do with the files being re-indexed or something.
