I bought a Freecom 1TB 3.5" USB 3.0 External from esquire today, but it doesn't work in either of my USB 3 ports, it pops up a prompt asking to format and when I click format it says it can't. It works fine on USB 2 and I have already formatted it on there. I know the USB 3 ports work as I plug my USB 3 flash drive in there. Any ideas, no point in a USB 3 drive that only works on USB 2.
