Hi,
As you can see in video, my WD Book Studio 2 has an unusual led blinking. I do not know if this is a led problem (maybe the led is near to get damage) or if is something bigger (pcb problem)…?
Do you have any idea.? Thanks.!
Testing the unit with a diagnostic software will be your best bet to verify if the drives are also failing.
