I want to download a lot more music and upload a lot more photos on my MBP so I bought a 2TB WD harddrive. (link: http://www.amazon.com/Western-Digital-Elements-Desktop-External/dp/B002QEBMCI/re f=sr_1_1?ie=UTF8&qid=1307759936&sr=8-1 )But If I move most of my photos and movies and music to there, how do I organize it? I'm thinking maybe I could move the whole iTunes and iPhotos together with all its files to the external HD? Also is there some sort of protection cover that I could buy for it? Also it says on the description: Designed for use with Windows-based computers. Can be easily reformatted for use with Macs. How can I format it for Mac? Maybe I should have gotten one designed for Mac?: http://www.amazon.com/dp/B0031WU8XS Should I try to reformat this one for Mac or return it and buy the pre-formatted for Mac version?
