Hello! I'm just getting ready to sell off a Macbook Pro, and I'd like to copy all of it's contents onto a external HD. The intent is to then use that external hard drive to put all of my content onto a new machine at a later time. I have an external HD that I put together using a 160GB HD that originally came in my first MacBook. It's inside a NexStar SX enclosure and connects via USB. When I originally did that, I think I was intending to use it as a Time Machine back up, but I never really went about doing it. When I plug it into my current MacBook Pro, it shows as a 55Gb storage. I'm guessing I partitioned it or something. SO, I'm really dumb. So dumb that I couldn't even find useful information searching the forums. I think what I'd like to do is just reformat that HD, and then copy my current computers contents to it. Can someone walk me through it step by step? I'd surely appreciate it.
