My Passport for Mac Will Not Mount

I have a 4TB My Passport that I purchased in May 2019. It functions as my Time Machine drive. Up until yesterday, it was working fine. We had a brief power outage, and when the power was restored, the drive did not mount. I have tried unplugging it, restarting my Mac, shutting down my Mac–just about everything. The drive shows up in my Mac’s disk utility app, but it is greyed out. When I try to run “first aid”, I get a message that the drive is not accessible. Is this a hardware issue or something else?
