WD MyPassport Ultra 2TB not showing up on either PC or Mac

[alips4xb1]

Hi; I have 2 TB WD MyPassport Ultra external drive. It was working fine the last time I used (few weeks ago) but now it wont show up on either PC or Macbook I own.

The light on the drive is illuminated (not blinking). The drive's vibration is too weak to notice.

It is showing up on device manager as well as bottom right icon bar of the Windows.

For info: I am using Windows 10 on PC & OS El-Capitan on Mac.

I have tried changing the cord. It doesn't work.
Other external drives I own work fine.
Tried updating the drivers & it did not work.

I am desperate it. Please help.

(Let me add that I am not a computer expert so any advice should be simplistic, please)

To add. I have tried uninstalling the device & reinstalling. It didn't work.

Device also does not appear in the device management. What I see is 3 or 4 unknown/unnamed devices of smaller sizes (Apart from the internal C & D Drive).

Welcome to the community, alips4xb1!

This seems pretty unfortunate! 🙁 I'd suggest you check on the Windows 10 PC if the WD My Passport appears in Disk Management. If you are able to see it there, share some screenshots.
Another troubleshooting tip you could try is using your Mac's Disk Utility to test the external HDD for defects. You can find a detailed tutorial on how to do that in our knowledge base here.

Hope it helps. Keep me posted!
