I have a Toshiba 500GB Automatic Backup Portable external hard drive, PN: PH2050U-1EWL SN: 42AKFBZCSRE8 , and when I plugged it in it did not show up under This PC but it did show up under disk management and drive management. Under Disk management I found that it was completely unallocated and it wasn't initialized. Upon attempting to initialize it, it would load for a minute or so and then give me an error saying that the device was not ready. I tried initializing it multiple times. The last time it worked was before I attempted to turn it into an Xbox 360 hard drive by formatting it and allowing the xbox to convert the hard drive into a format it liked or something like that. How can this hard drive be saved, or can it even be saved? If you need screenshots just ask. EDIT: the hard drive also shows up under devices and printers.
