I recorded some saved programs on my Dish Network DVR 622 to an external hard drive that formatted it for that purpose according to their instructions. Can the external hard drive now be reused by being hooked up to my standalone computer and reformatted or have I lost it because of that use? If so, how do I do it? I do not want to save anything on the drive--just format it and use it for a different purpose. I no longer have the Dish DVR. When I connect the external drive to my desktop I do not even see an icon for it in My Computer. Thanks for any help.
