Original Drive still works in the Duo, but it makes some pretty terrible clunking and scraping noises when it tries to read/write in a few spots. When the drive still had a System install on it, it would boot, but it would literally take hours to do it. Unfortunately, I don't have access to a Duo Dock (though I'm starting to think I should take someone up on an offer of one and have it shipped).
