It sounds as if your going to need to replace the receiver as the hard drive has an error on it. I assume you can record live TV. There are also few 510's in the Dish Network service area throughout the country so my suggestion is to have Dish send the receiver to your home as opposed to creating a work order for a technician to come to your home as it will be hard to ensure you get the 510 back.If you decide to upgrade to a HD receiver try to get a model that does not have the internal hard drive but also has the expansion port on it. There is a one time fee to activate this port of 39.99. This amount will be recovered in the first year by using an external hard drive eliminating the 5.99 DVR fee every month. This option also allows you to have better control of your recordings and makes them portable. They also will not be lost by replacing the receiver. If you are a real big tv fan check out the sling box offers. Thanks for using Fix Ya.
