I've lost all my Doctor Who episodes that I ripped and put on my external hard drive, all my Torchwood and Sarah Jane Adventures episodes are still there. This isn't the first time it has happened. It deleted all my Doctor Who episodes a couple of times before. Normally the episodes come back the next day, but today, it hasn't.
Is there anything I can do to put all my Doctor Who episodes on my external hard drive and not have it delete them by itself? I have to rip them all over again.
