Turns off the power save mode on the hybrid hard disks in the system. If you enable this policy, the disks will not be put into NV cache power save mode and no power savings would be achieved. If you disable this policy setting, then the hard disks are put into a NV cache power saving mode. In this mode, the system tries to save power by aggressively spinning down the disk. If you do not configure this policy setting, the default behavior is to allow the hybrid hard disks to be in power save mode. NOTE: This policy is applicable only if the NV Cache feature is on. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Disk NV Cache!Turn Off Cache Power Mode (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\NvCache!EnablePowerModeState
