I can't access my external HD.

This is the error that I get when trying to run first aid in disk utility:

Running First Aid on “WD My Passport 25E2 Media” (disk2)
Checking prerequisites
Checking the partition list
Problems were found with the partition map, which might prevent booting
Partition map check failed because no slices were found. : (-69770)
Operation failed…

What can I do?

I have a MacBook Pro mid 2014 with Catalina 10.15.14

  • A "slice" is usually terminology used for RAID devices. Is this one of those devices with two internal drives? That might explain some of it... – Steve Chambers May 15 at 12:36
