I just purchased a hard drive to record programs with my GeoSat Pro DVR 1100C. It is a Toshiba Canvio 500 GB portable hard drive. I can't really figure out how to set up the drive. The instructions for my receiver were not entirely clear about what to do first. Do I use the receiver to format the drive, or do I need to do that with my PC? I plugged the drive into the receiver and tried to format it from the menu. However it doesn't even act like it recognizes the drive as being there. That leads me to believe that maybe I should format with my PC. I have considered that there could be another issue involved. I did not realize when I purchased the drive that it does not have its own power supply, but rather draws its power through the USB cable. Could this be a problem?
