Hello. I have a problem connecting new hdd WD Green 3.0TB. I connect it to my MacBook Pro 8.1 with OS X 10.9.4 via USB digitus (http://www.digitus.info/en/products/archiv/usb-20-ide-sata-cable-da-70148-1 /), but after connecting my disk does not appear in disk utility. Digitus USB is fine. When I connect my the old drive (WD 1.5 TB) everything works perfectly. Please advice. Thank you.
