My 3TB Elements suddenly not working on my Mac. The power is always connected to ups, and the usb cable only connected to PC when needed. Normally the Elements led light turn on (and blinking) only when we plug the USB cable to the computer, but this time it’s always on when I turn on the ups. But when I connect the usb cable to pc nothing is happen. The led is not blinking, the Elements is not showing on Disk Utility either. I’ve tried on every usb port and in my macbook pro with same result. Any thought?
