This sucks... When I activated the external storage I asked that if I had two dvrs could I swap the hard drive between them. I was told yes before activation. This worked for about two weeks. Now when I try to swap I get this 866 warning message saying that it will delete existing contents of the hard drive if I reconnect it to the second dvr. Upon calling Dish they confirm that this is now the way it works and was sorry. Was any one else under the impression that you could connect the same drive to multiple dvr's and not lose your shows.
