My EHD stopped being recognized by my hopper. It acts as though I never plug it in, the drive doesn't register any attempts to read from it. I'm switched to a different drive, different USB cable and from back to front port with no luck. Dish rep was stumped because "if it doesn't generate an error message they cant troubleshoot it" and left me to literally wait until it either starts working again or gives an error. Has anyone else ever had this happen and is there anything I can do. The Sling adapter does get recognized from the USB port so it's not that the port is blown out.
