I got new dish receiver several months ago. My wife wanted to keep her recordings from old receiver. The Dish tech said that I could use my external HD to download from the old IRD and upload to the new. He didn't tell me that it may not be possible to use the HD again on my computer. The IRD formatted the HD and all went well until I tried to use the blank HD on my computer. The computer can't see it. I'm not trying to watch the dish recordings on the computer. Once the recordings uploaded to the nre IRD, the HD is blank. I called Dish and was told that they know now way to reformat the HD to use with the computer. I told her that the tech guy should have told me this before hand. Does anyone know how to reformat this ext HD? Any help greatly appreciated!
