WD My Book 1TB External Drive unrecognised by all devices

So I was using my drive for a week or so to watch TV shows from the computer on the TV.
It was all working great! Then one day while I was cleaning up I unplugged the drive from usb in the tv and the AC.
Since then the TV and the PC and the laptop will not read it. Can’t even get a password screen to come up.
Looked at device manager and its not there either.
Anyone else got this issue? Need it fixed!!!

Hi there,

try on a different computer to see if the drive shows up, does the drive make any sounds when its plugged in ?

Hi ArMAk,
I have tried it on mine & my mums computer.
The lights on the front just flashing consistently.
It does make a slight sound like a CD starting up but then stops.
