I called Dish this morning and paid $40 for them to activate my VIP722 USB port. I was told to wait 15 minites but I waited an hour before rebooting the 722. I then plugged in a 160 gig WD Passport. I left it for 3 hours listening to it going "click click" thinking it was being formatted. Realizing that was long enough I plugged it into my PC but it was still readable under Windows. In the 722 menu under Multimedia the USB box says "no USB device detected". Do I need to delete the existing format before plugging in the drive?
