I switched out hard drives (500GB to replace a 160GB) to give me more memory on my computer.
The repair went swimmingly. The online instructions were perfect. Thanks for the help. I had some trouble though using SuperDuper to clone my hard drive. The computer froze multiple times while trying to clone onto the new drive. I ended up just re-installing OSX, and using time machine for the backup.
Back up your drive with both SuperDuper and Time Machine, in case one doesn't work. I used separate external drives for this.
Also, make sure you have all the tools you need before you start. I had the wrong size Torx wrench, and had to stop in the middle of repairs to go get one.
