I just purchased a 13" macbook pro. I previously owned a 15" MBP that I bought four years ago and never upgraded the OS on it, so I was still using Tiger. Now that I have the new computer and time machine to go along with it, I'd like to start being more proactive about backing up my files. I don't want to purchase Apple's Time Capsule for two reasons: the price, and I've read that it is not possible to partition the drive for other storage capacity besides backing up. Ideally I'd like a drive that I can store movies/tv seasons on in addition to the time machine backups. Does anyone have any recommendations on reasonably priced external hard drive that will suit my storage needs and work easily with time machine? The hard drive on my laptop is 320GB , so I'm also wondering how large of an external I need to purchase... was thinking 500GB but I really have no clue. Thanks!
