Welcome to the community, @Alex!
I'm truly sorry to hear about your personal issues what lead to them.
I'd advise you to try swapping the USB cable connecting the WD My Passport and then check how it appears on both computers. Afterawards, run the QUICK and EXTENDED tests from WD's Data LifeGuard Diagnostics for Windows
. This utility will help us determine what is the health and SMART status of the external drive.
If the files are so important to your wife, I'd advise you to get in touch with a professional data recovery company instead of doing data retrieving attempts by yourself. This is potentially dangerous to the content, especially since we are still not aware of the damage on the WD My Passport. You could refer to our Data Recovery Partners
If this is a brand new WD Passport, you should still check its warranty
. If it's covered by us, you should be able to send an RMA request to our Customer Support
and get a replacement after a successful data recovery. For more details on these procedures, check the WD Warranty Policy
Keep us posted with the troubleshooting & your questions.
