Thanks guys! Ok, next question. I have purchased an enclosure and connected it to my other computer. I have opened disk utility and there are choices of ways to erase data 0, 7, and 35 times. I don't have anything on the computer that is government secret or anything like that, but I do wish to erase all of my pictures, documents and music. I do plan to sell the computer to someone I don't know. Which method should I choose to do this? Thanks for your help! Candace
p.s. Nick..Apple care told me if I bought another computer they could credit me the balance of my old apple care to use towards a new computer...is that not correct? Let me know your thoughts..
