I'm very new to OMV - barely a day old - and I was able to setup my HDD and file shares, install a DLNA service etc. OMV for now is installed on an Raspberry Pi 2. The HDD is connected to the RPi Model B. I've setup my SMB/CIFS file shares and they are accessed from my Windows and Mac machines. I've observed that the HDD does not spin down if its not being accessed. It stays ON all the time. Under Physical Drives I have set the power usage to be minimum with spindown but it does not look like its happening. Any suggestions on how I can get the HDD to spin down?
