WD 4tb external hard drive won't turn on


#1

My WDBFJK0040HBK-0A External hard drive isn’t turning on. I’ve had it for a few years so I’m not sure about warranty, but it just stopped working randomly. When plugging the cord in, the blue light will blink but not turn on. I bought a replacement ac adapter, thinking that was the problem, but it wasnt.
