Everyone knows that when you hear the hard drive "clicking," it's the start of something bad. So I took pre-emptive action and ordered a new hard drive—bigger and faster.
Piece of cake. With the instructions up on one computer, I went through the steps one-by-one and, 35 minutes later—VOILA!—the new hard drive started up in the old computer with ease. Everything was working as it should. Exhilaration! Relief! Pride!
Don't be afraid. Everything works just like ifixit says it will.
