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
