@Colin : I just tried "sudo pm-powersave off" on my Asus EeePC 1005PE (after having applied latest updates and rebooted, kernel 3.2.0-19-generic).
It doesn't bring any improvement. I'm still getting about 1 HD start/stop per minute, system doing absolutely nothing and not even connected to the Internet.
