So I first owned a PC and then I decided to get a 2.4GHz 160gb macbook for college, and now I am looking for an external drive that can work for both my pc and mac. I am new with the external drives, I don't know much about them. I usually transfer music files from my PC itunes to my mac without a problem and all the pictures that I use are jpeg so I am always able to move them back and forth between my pc and mac with a flash drive. For now I only plan on backing those types of files my itunes music and pictures. My plan is now to get an external hard drive and transfer all those files from my PC so I can use it with my macbook (it's way better then my PC) without using to much space from my macbook's internal hard drive. So my questions are: is it possible to use the external hardrive kind of like an internal drive, in the way that I can pull the music files and pictures that I want to use without to much delays? can I view whats inside the external drive? How can I do this? and which external drive would work the best? I am sorry if this is confusing, I would really appreciate the help tho. Thanks.
