I have an external harddrive that is connected to an old VIP 211K receiver that is on its last legs. I know the Hopper is a different format and cannot be connected to the older EHD. Does the Wally use the same format as the 211K? Will my 7 year old 2tb EHD work when plugged into a Wally or can it only work when plugged into the 211K. Any information would be greatly appreicated.
