Im wanting to upgrade my macbook aluminium (late 2008) hard drive from 250GB to 500 GB. I believe it has to be a 2.5" SATA drive, which i have found. Now what im looking for is some (really) simple step by step instructions on how i go about doing the upgrade without loosing any of my stuff Here's my current plan. 1. Back up everything onto an external hard drive using time machine. 2. ***** myself and be too scared to do anything for fear of loosing everything! I obviously need a better plan than this. Any help would be greatly apreciated!
