Input: The instructions with this product make no sense at all.  I tried following some of the suggestions of other reviewers with no success.  I plugged in both hard drives, double-clicked the button but nothing flashes.  A light comes on when I push the button but I don't see any flashing or progress bar.  There is no way to know if it's working.  I'm returning this.  Total waste of time.

Product simply doesn't work
