hello all. this is my first post so go easy on me. i have a macbook 2.0 unibody. i just bought 500Gb internal hard drive and i want to replace the stock 160Gb with it. how do i move all my stuff from my old drive to the new one? i don't have the cash to buy an external hard drive just so i can move my stuff back and forth, i will have no need for an external right now since i have a 500Gb internal. someone told me to get an HDD caddy and use the stock drive as an external. what i am wondering is, will i be able to transfer all my applications without having the install files (i deleted all my install files as soon as i installed them). is it going to be a simple "drag and drop" kind of deal and every file knows exactly where to go? i just don't know what complications might come about. if anyone has any experience doing this, i would appreciate any help. thank you
