When I arrived to work the NVR was not displaying video or lights on the front panel but the fan was operating.  I called the support line and received the VM.  After leaving a message I began to trouble shoot and started to unplug everything from the unit.  Down to just power and video it would still not boot.  

I opened the unit and began to unplug HDs.  Down to one HD from three the unit would boot.  I plugged the first HD back in and it still booted, then plugged the second HD that I unplugged, back in and the unit failed to boot.  I believe I have a bad HD.  I am wondering what I need to do to verify this to support and also if I have any warranty for this HD.
