I have installed the above MB with Windows 7 64 bit. I have a Verbatim\nexternal USB3 hard drive. When I connect it to the USB3 port on the MB it\nsays that I need to format and then I get an error message saying that\nwindows can't format the drive. I have the latest usb3 driver from Asus\ninstalled. V 2.0.4 It works fine on the USB2 ports. Does anyone have any\nsuggestions?
