I'm thinking about getting a bigger HD for my MBP. I'd rather not start install everything fresh. Is there an app where I could hook up the new HD with USB and mirror the contents of my current drive to my new one? Does it work well or will it cause issues? Also, can someone recommend a 500gb 7200rpm drive? Newegg only has this one... http://www.newegg.com/Product/Product.aspx?Item=N82E16822148374 ..and the reviews don't sound too good.
