hey buddy this is not a big issue
windows 7 is showin that windows can not recognize it beacause the drive size is 2 tb right?
the it is to big size for your motheboard.
your motherboard is not able to run with 2tb
you have to give connection to the main usb port.
1 or 2 port of usb on motherboard are directly connected to the powersupply
this port can run your 2tb hdd
ok try it
