Energy Saver problems


Hi, for some strange reason when I log out and leave my Mac unattended for 10 minutes, the monitor will go to sleep and one hard drive will spin down, then after another 10 minutes the slave drive will spin down. The hard drives will then wake and sleep in 10 minute intervals there after. I have not been able to find a way to turn it off even if I log on under root or the primary admin accounts. All the users have the Energy Saving settings turned off, though originally it was turned on. Anyone know whats going here? Is this a bug or a feature? Or perhaps experience this themselves?
