I had to fast-forward parts of video, to skip the tedious parts (unscrewing, re-screwing). I think I covered everything in the video, but if you have any questions, leave a comment.
BTW, the hard drive replacement seemed to have cut my battery life by about 3 hours. This is a major downgrade to me, personally, even at the slight performance increase, so purchase this hard drive at your own risk. The main point of the video is to show the actual physical steps for the replacement.
