I'm using Windows 7 , I set my drive to sleep after 10 minutes and it works but, when I shut down windows my hard drive resume from sleep. Why? It shouldn't keep hard drive sleep and shut down the PC ?

When you shut down Windows, various things are written to disk, swap file is modified, etc. If the disk is asleep, those items can not be written or modified on the disk, which is why the disk is powered up before the system is shut down.

Because it needs to wake up the harddisk to save user and system settings. Otherwise your settings (and all ongoing works in that session) will be lost.
