WD MyBook Win7 - hibernation off?

I want to turn off the hibernation of my three new WD MyBooks (USB3) for my audio software. I have done the settings mentioned on the WD support page (How to disable power management settings), but it looks like the PC does now work without energy saving, BUT my the MyBooks go again to sleep after some minutes.

Did I understand it correct that I can turn off hibernation on my MyBook? 

Many thanks for any info!
