My Passport 4TB not mounting

[bijumathews]

The external drive doesn’t mount and light keeps blinking. It failed the complete drive test.

if it didn’t mount … how could you have done a complete drive test ?

I meant the hard disk wasn’t showing on the Mac. And I couldn’t view contents of the HD. I am attaching a screenshot.
Is there any way to get it working?
