Ok bought a WD passport 400 GB external HD, found out that I needed an external HD with a power supply, so returned it and got the 640 My Book. Hooked it up and got the old 863 Feature Not Supported Info Screen. As I tried all kinds of crap with tech support....uuuggghhhh, I jumped on and started some research and found that all i needed to do was hook up to my pc and format the external HD, did it and it took off like a pro. I then proceeded to inform the tech support folks how to fix the issue next time so they new, the tech support lady completely ignored my resolution and proceeded to tell me her Eng Support Group suggested sending me a new 722, I said aaahhhh, sure thing send it out! I am shocked that something this simple is not communicated to the tech support group @ Dish. Man a damn email to all their tech support folks would get it taken care of....ohh well a new 722 for me. hhhhhmmmmm I have a 622 upstairs also...mmmmmmmuuuuuuhhhhhaaaaaaaa!
