Bought one of those 500 GB Samsung drives - but, of course, the head of the screw holding down the old HD in the new unibody book stripped. Probably a combination of a crappy screw, and me not quite being careful enough. Anyway... I know about the ways people handle stripped screw heads--superglue, Dremel, screw extractors, etc. I don't particularly want to mess around with that stuff, and I'm not sure those methods will work on such a tiny screw. Any insight into how, if at all, the Geniuses at the Apple Store will handle this one?
