Here we go. I have a 40GB, Hitachi laptop hard drive which I have been running in a USB enclosure. Just to save files, music nothing too big. My computer no longer recognizes it. It does show up under disk management as an EISA configuration and a primary drive. It also exists in disk manager after I unplug it from the computer. I am not worried about the info on it so if I have to format again I will but any ideas would be greatly appreciated.
