Hey. I have an airport extreme, gigabit/wireless-n router. I thought about plugging in my 500GB external hard drive, the one where I keep all my movies/tv shows that I didn't want to store on the macbook's internal hard drive. Well, I plugged it in, the windows and mac side detected it, but it can't read any of the files originally I had on there. Its blank. The space is taken, I just can't see my older files. Any ideas?
