Hi, I bought the 500gb scorpio Blue drive from Western Digital. I'm gonna install it on my unibody macbook. I have never done this before because I have always used imacs so I was wandering if somebody could walk me through the steps necessary after the physical installation of the drive (I will follow the manual for that bit) I.e. the installation of leopard and formatting the drive etc. MANY MANY THANKS. Edit : What are the rules/icons next to the usernames???
