I have the Pace DC900X DVR and want to attach an eSATA drive to it via the external connection. When I plug in my external hard drive nothing happens. My tech when he installed the DVR system recommended attaching the external drive for more space. All the research I have done shows that this device has the ability to add an external hard drive deactivated but will be opened with future updates. I wanted to know if that update was out and if so how do I apply it and if not when will that be available.
