The WD Drive Utilities works when My Passport Ultra is plugged into a USB 2 port, but not when in a USB3 port. I can read and write OK under USB3, but when I run Drive Utilities under USB3 from the Windows 7 Start menu it just gives the message “Attach a supported WD disc.” This happens if the disc is already attached or if I attach it after the message appears. The utilities seem to work OK under USB2, so I am hoping that they still apply when I go back to using USB3. Still, this is definitely seems like a bug.
My USB3 is a 4 port Anker USB 3.0 PCI-E Card in an HP p7-1280t computer, the USB2 ports are the built in computer ports.
