hey everyone. i just ordered my first mac (mbp 13") and am really excited. I currently have an external hd i use with my old pc laptop and wish to use it as a time machine back up device for my mbp. i still have a lot of files on there (itunes, homework, etc...) that i want to move to my mbp hd first. then format my hd so that i can use it with time machine. could anyone give me a tutorial (here or a link to youtube) that would explain how i should go about doing this? i would appreciate it.
