If problem persists try another port

Welcome to the TH community, that1nob!

I'm sorry to hear about your issues with the 1 TB WD drive! Have you tried plugging it externally via a docking station or an external 3.5" drive enclosure? I'd suggest you give it a try and see how it will get recognized. You mentioned that you have also attempted to plug it in another computer. How did the other system see the HDD in BIOS and in Disk Management?
If this is, indeed, a defective brand new WD drive, you should definitely check the warranty on our website. If it's still covered, you should be able to send an RMA request to our Customer Support and get a replacement.

Hope this helps. Keep us posted with the troubleshooting!
