I have 2 non-system SATA HDDs which are not mapped to a dir and normally kept 'offline' on my Windows 7 OS. Even this way they spin up from time to time, including but not limited to windows update times.
It's easy on Linux but, what is the best way to spin down a HDD on demand using as small 3rd party software as possible on Windows? Or even, is there a 3rd party software allowing this?
