Lock light when powering up issue?

I was using my 1tb wd external fine, then one day I go to turn it on and there is a lock that is lit up on the Drive and now my computer does not recognize it, nor does it seem to make any noise.  It seems as if it was locked up and needs to be unlocked, but I never even used the software and set a password for it.  I only use it for copy and pasting.  Can someone please help me with this?  I already tried tech support and they were not too helpful.  I tried different chargers, usb cables, computers, it does not show up anywhere, not even in the disk management section of my computer.  Thank you for reading this. 

I am having the exact same issue with the exact same device. I never set up  a password and smartware even says that I don’t have one set up!
