I have a WD Black P10 and was trying to find a way of turning it off after a period of inactivity. I downloaded the WD Drive Utilities sofrware for my PC but it doesn’t appear to recognise the WD Black P10. Is there a way of setting this functionality for the WD Black P10 as I have it connected to my Nvidia Shield Pro and the only way of turning off the hard drive is to completely power off the Nvidia Shield Pro when it’s not in use?
