After PC is idle a while, all HDD's spin up?

[CreeDo]

If my PC is idle for, I dunno, 15 minutes... instead of putting drives to sleep as I'd expect, it does the opposite... all 4 of my internal drives spin up (from a state of being completely stopped). So when I go to bed it's like... *silence* ...click-whiiirrrrrrrVWEEEEE VRMMMMM REEEEEEEEEEEeEeEeEEeeeeeeee

...

So yeah, why is windows doing that? I have no screen saver. The display goes away after 10 minutes and hard drives are set to sleep after 20. Entire computer is set to sleep never.

Make sure you dont have either Hibernate or Hybird Sleep activated

Hibernate writes all stuff to disc and then shuts down computer to restart in that state

Hybrid Sleep does both. Keeping info in ram so it is quickly accessible and putting info on HDD's so if it does shut down (due to power failure etc) then it can resume from hibernation state.

So if you have Hybrid sleep activated it will do that.

If you dont have either? I dont know. I will need a few minutes

Maybe something in the scheduledtasks is set to run when idle.

or maybe Search is logging files while idle

Process Monitor

^ for 3rd party solutions (as there usually is one) you can use this program to monitor all of the programs that run on your computer. let it idle for the 15 minutes and then when it spins back up, note the time and check the program to see what is acting up
