External WD Harddisk: Mounting issues on a Mac with the APFS file system

Need advice on my harddisk issue:


  1. Disk Utility's First Aid was unable to mount or repair the drive.
  2. Using the sudo pkill -f fsck command in Terminal to forcibly stop any file system checks did not resolve the issue.
  3. Restarting the Mac with the external hard drive connected was not successful in resolving the problem.
  4. The hard drive is recognized by the system, as evidenced by its presence in Disk Utility, but it is greyed out and not accessible.


Many thanks!

The Extents Tree is a data structure that indicates exactly what blocks are holding each segment of a file. it needs to be perfect. if the Extents Tree is not perfect, you could get blocks of other files in the middle of a file you are working on, or the next file written might clobber blocks already used for an existing file.


if Disk Utility can not repair the drive, it needs to be Erased. If this is your Time Machine backup drive, you can always ADD an additional backup drive at any time, and Time machine will create a new stand-alone backup on the new drive, then every-other backup goes to every-other drive.
