First, unplug the DNR-322L power cord for 30 seconds and plug the unit back in and see if that corrects the issue. Next, when you press the Reset button, there's a specific procedure to follow. While the DNR-322L is powered up, press and hold the Reset button for > 9 seconds. This procedure will reset all user settings/configurations to the factory defaults, but should not impact the HDD configuration or stored data.
