I've found threads on this topic before that the question was never answered, just pages of comments why the person didn't just replace the receiver. So from the start I'm not asking your opinion on why I don't replace the receiver, because I own the receiver, I've found an exact replacement new hard drive for $28.00, and if I swap the receiver I'll have to pay rent on the receiver and DVR option. So with that said, when replacing the HDD in a VIP722 (non K) receiver will it self format when installed, or is there anything I need to do before installation? Again the hard drive being installed is the exact brand, model # and storage capacity and the one that gave up the ship. Thanks in advance for any replies.
