It couldn't hurt. But like I said earlier bud, there's no need to rush and replace it. It was probably just a bug that was fixed by one of the things you did earlier. Or maybe it was just having one of those days. Seriously, computers can do odd things and then you'll never be able to reproduce it again. But anyways, yeah, If you know how and feel comfortable, I'd say check the connector. Laptop hard drives usually have a screw holding them in place, so it's unlikely that it got jarred loose, but you never know.
