I was using my WD My Passport Ultra 1TB hard drive up until recently on my XBOX ONE until with no apparent reason it stopped working/being recognised by XBOX? I removed it and attached to my PC (Windows 7) and laptop (Windows 8) to see if it was working and to see if I coiuld reformat it. The drive is recognised when I look in device manager and the light flashes when I plug it in and I can hear the drive spinning but when I try to access the drive to reformat it is not showing in Windows explorer so I can do nothing with it. Both the PC and Laptop do the same thing, I have attached pics to show what I mean.
Anybody got any ideas on how to rectify this?
