Excuse me, but I think that the whole "windows shows not this problem" approach should be entirely revised.
On my Dell Vostro 1500 with a Seagate st9160823as windows XP sp2 and ubuntu Gutsy "pre-fix" behave EXACTLY the same way with a rather aggressive (and noisy) power management.
Not only, but a thread on a italian tech forum I read, showed the same unpredictability: http://www.hwupgrade.it/forum/showthread.php?t=1595762
To summarize some posters had problems ONLY with Ubuntu, some ONLY with windows, some had problems EVEN when the laptop was AC-powered.

There is a big chance that this problem is BIOS/firmware related and it could be somewhat more useful if any of the posters could effectively test the behaviour of their systems under different condition and check hdparm result before and after trying:
1 hr with windows (idle)
1 hr with linux (idle)
1 hr with windows (benchmarking or working)
1 hr with linux (benchmarking or working)

both on battery and on AC.

I've done it before posting.
