I have 2 211's which I would like to connect harddrives to. Called dish and they said I can only have one harddrive active at a time. Said I could disconnect one and connect the other and it would work but that doesn't do what I want. I bought the extra receiver with a tailgater for camper but would like to be able to use it in house. I have a tech coming tomorrow to help me with the wiring. Dish told me I could just put a splitter on one feed and run it to the other 211 but that didn't work. Second receiver wouldn't power up. Both receivers work fine when I connect the second receiver to my tailgater so I know the equipment is good. Also, when I connect the hard drive to the second receiver I get the message to call dish and activate and error code 790. In reading other threads I see references to connecting the second receiver with a switch of some sort. I'm assuming the tech will help me with that but would like your input on the second harddrive issue.
