The short answer is yes. Everything works, I've even installed Vista SP2. However, I ran into a problem with my machine/HD combo that I'm still working out. See this Question/Answer Why does my new Hard Drive cause system shutdown Also here is my Discussion about it. I'm currently awaiting a 5400 RPM drive from Seagate to see if that will work in my situation. I'm not sure what I'll do if it doesn't. YMMV.
