I have been using my Iomega external hard drive for my xbox360 for about a year. I have had a few problems where it will not show up in my storage device list. It usually shows back up after I unplug it a few times and re-insert it back into the port but for about twenty four hours I have been unable to get it to recognize that it is plugged in. The hard drive's power light is showing, so I know it is connected but it isn't being recognized by the console itself. What are some suggestions as to what I do next?
