I have a MacBook with an 80GB hard drive. Right now I have my iTunes library on an external 120GB hard drive. My iTunes library is getting close to 50GB now (including videos and podcasts). I am thinking about buying a larger internal hard drive and installing that so I don't need to use the external drive so much but I don't really know the best way to do this. I know how to remove and install the new drive but what I'm unsure about is the best way to back up and restore so that I can pretty much have my system exactly like it is now. I am a recent Windows switcher so I don't have a lot of experience with OSX yet. Any suggestions would be greatly appreciated. Thanks.
