Windows 10: Trouble Seeing External Drive

I have been using a WD My Passport external drive since 2006. Beginning in Dec 2019, none of my laptops can "see" the external drive when I plug in the USB cable. Using Disk Manager, it says that there are 931 GB Unallocated and disk not been initialized. What happened? Looking at the logs, it shows that the disk was "migrated" on Dec 5 last year. What does this mean? How do I get back into the drive?
