Hello folks, what I was trying to do was manually or automatically turn off the HDD in my system for the following reasons: 1. Silence 2. Extend the lifespan I have a HDD that I only use for mass storage - big documents and CAD models. Also I have to note that I use it very rarely, like once in a week or sometimes just 2-3 times a day. I use SSD as my main drive and I keep everything I access regulary on that drive. I've tried using the power plan option to turn off HDD after 6sec of it being inactive, but although the drive isn't being accessed at all, it takes up to 10min for it to turn off (stop spinning). I was also wondering if using the 6sec time to turn off HDD could impact my SSD's performance, or it will never go inactive due to the OS being installed on it? It would be awesome if there was an option to turn it off manually and then let it start spinning when I access it, or leave it completely turned off untill I access it and then turn it back off manually. I'm using a define r5 and my system is unhearable, at least for me, in every scenario except gaming and editing/modelling. I am also using a Maximus VII Ranger so I was wondering if there is an option I could use in the bios or some of the board's software? Win 10 enterprise x64 Thanks in advance.
