I am looking for a nice portable external drive for my macbook pro. I need something bigger then 80gb or so. I would like a drive that doesn't require an external power source. So, I guess firewire might be out of the question. It must work in both mac and windows. For the time being, we are recording our podcast on a windows machine since the Alesis firewire mixer doesn't work on mac intel. Anyway, I am doing the post production on the mac and I wanted to have some extra space for MP3s movies and what not. Anyone have some recomendations ?
