I have a first generation Xbox that's seen A LOT of use since I bought it. Lately it's been running kind of crappy the hard drive makes a lot of the "clicking/grinding/thinking" noises when playing games. Is it possible to pull the harddrive and defragment it without disrupting the OS on it? BTW, it's completely stock. I'll probably need a shopvac to get the dust out of the thing I'm betting.
