External Hard Drive usable in Windows, but not even showing in System Information on Mac

My external WD Passport USB has been working absolutely fine in Windows 10, but has not been showing recently in my Mac.

I've force formatted the Hard Drive to exFAT in Windows, and is still working and usable.

But on my Macbook Pro (MacOS High Sierra), the drive isn't visible in diskutil, Disk Utility or even System Information (The USB Bus isn't showing).

The drive still spins, and the activity light is constant - but as far as I can tell it looks dead.

This is a new one for me, and I have no idea on what to do next and everything points to the drive being healthy.
