Could people please test setting DRIVE_POWER_MGMT_BAT to 127 by default? That's the first value which actually does permit spindown. Please change that with
sudo gedit /usr/lib/pm-utils/power.d/harddrive (or your favourite editor) and set line 14 to DRIVE_POWER_MGMT_BAT="${DRIVE_POWER_MGMT_BAT:-127} If this doesn't help, I'll modify the maverick version to use 128. This will take away a lot of the power saving, but if it works so poorly for you (i. e. the people affected by this bug), we can't help it.
