I have WD My Passport Essential 320GB and for no reason, Windows 7 64Bit and WBFS Manager does not recognize it anymore. Just as I wanted to add some more games into the HDD, I plug it in and nothing happen. WBFS Manager does not detect it either. I didnt make any partition on the HDD, the whole HDD is WBFS, formatted by WBFS manager 3.0 and so I want to be sure that is not the faulty HDD, I plug into Wii again and I can load and play game without any problem. I try everything I could, try different USB port, restart pc, reinstall USB driver etc. Also i couldnt format or delete the volume of the drive because Windows doesnt see it, obviously. Anybody got any idea?
