WD MY PASSPORT ULTRA not showing up on Mac

I bought a 5TB black WD My Passport Ultra and it doesn’t appear on my Mac. I have MacOS Mojave. When I plug it in, I can’t even see it on disk utilities. I have an older 4TB WD My Passport which shows works perfectly, so the connection on my Macbook is not faulty. Can I fix it or should I return it?
