Running Feisty, Dell XPS M140, with a Hitachi HTS541060G9AT00. Same situation, always noticed LOTS of spindowns but never thought much until it started really bugging me. Installed smartmon and found 154153 load cycles with 308 power cycles.
Running hdparm -B 255 /dev/sda has fixed it for the time being.
