I'm not going to pretend like I know what you just said. Can you explain it in dumb-people language?
My PB's drive and my external drive are both formatted to Mac OS Extended (Journaled). Does that help you figure anything out?
Also, the external is brand new, so I don't have to much on it. A full erase is a possibility if it'll help something. Just let me know what to change.
Daniel.
