USB causes Phenom to Freeze Up

When I try to use a USB drive other than the one shipped with the Phenom, the screen freezes up. I purchased two new USB drives identical to the one I received with the Phenom, but they do the same thing. I’m guessing it is related to formatting of the USB drive. Can you help with how to properly format a USB drive to work with the Phenom?

I believe its Fat32…

The phenom usb drive is FAT32, but I format the new one as FAT3w and it still does not work. I’ve tried both windows and Mac.
