I think kernel32 - DeviceIoControl may help you.
I don't have an example though.

What do you mean by "TURN OFF"?

[BlackCatSLO]

If i got i right he wants to power off HDD like its done in screen saver Power settings. I suppose its something like Sleep, but im not sure.

[BlackCatSLO]

There are a set of Power related API's (http://msdn2.microsoft.com/en-us/lib...9(VS.85).aspx). I've not studied them in depth, but it looks as if you can dynamically change the current Power Policy, however looking at the structures involved, it seems that you can only power down all the spindles rather than select a particular device. (But ,as I said, I've only had a quick look)
