Hey, so I recently upgrade to Lion from SL, no problems at all so far... but now when I plug in my external hard drive (which I use to store media and big files, etc.) the drive is noisy as hell! The head(s) on the external drive are moving all over the place and making tons of noise... Anybody know why? I'm thinking maybe Lion has some automatic defrag routine or something for external drives that snow leopard didn't have? That's the only thing I can think of. I'm not running any programs that are even using the external drive. Just having it plugged it makes it super noisy... So what's Lion doing with it? Any ideas? Thanks!
