I posted about a month ago about replacing my hard drive and I've finally done it. It was pretty easy to do and now I have an 80GB 5400rpm where I used to have a 30GB 4200rpm drive. It's noticeably faster now but I can hear the drive spin and sometimes I hear it click. I guess I shouldn't have chosen WD and should've gone with Hitachi or Toshiba instead.
Anyways, I said I'd post when I did it so, voila.
