How can I unlock my thumb drive on a Mac? (Part 1)

Episode 978 (2:28:38)

Mark from Syracuse, NY

Mark has two thumbdrives hooked into a PogoPlug connected to his MacBook Air, but now his drives are read only. Leo says that drives can end up read-only when they're damaged. If he removed the thumbdrive without ejecting it, it could have damaged it. Leo says he can pull the data off it and then reformat the thumbdrive.
