Hello! Sorry if you've seen this a hundred times but... I have a MacBook Air and all my media files are on an external hard drive which I previously used on a PC laptop. I've heard something about NTSC (?) and that mac's can read but not write to these. So two questions... 1. If I want to buy an external hard drive which will work very nicely with my macbook air (preferably wirelessly), what do I buy? 2. Can I simply drag and drop the files from my PC external hard drive to my new one, wait a few days for it all to transfer, then start using it with no bother?? Thanks a bunch!
