I’ve had a WD elements 1TB storage for just over a year- have stored all my families photos on it. Now my mac as stopped recognising it at all. doesn’t show up in disk utilty- it’s turns on when plugged in (can see light and hear disc spinning) but just doesnt mount the mac
Have you tried using a different USB cable? If the unit has a power adapter also try to connect the power adapter directly to the wall see if this helps.
