I have a MBP 2.16 ghz with a 120 gb hard drive. I have been using this external hard drive to store and playback video files: http://www.bestbuy.com/site/olspage...tech&lp=12&type=product&cp=1&id=1198286609141 I also have a 120 gb external hard drive as a time machine backup. Would it be possible to replace my hard drive with the 320 gb external, then restore everything on my original using the time machine backup? Im not worried about opening up my machine, but I'm not too familiar with how time machine works for restores. Thanks for the help.
