I tried getting an external hard drive added to my account tonight via the tech chat on dish.com. I've got a vip211k, (2) 301's and a 311. When the support tech tried to add the EHD activation he said it prompted him to upgrade my standard def receivers. I'm not interested in changing out the SD receivers for various reasons. Maybe one of the DIRT folks can assist in getting the EHD activation added to my account?
