My Book 8 TB Drive

Recently had two sudden power losses and my WD MyBook 8TB External Drive now is not recognized by either mac that I use.

The light in front is lit up and the drive is ticking almost like a clock, not sure if it’s dead or not.

Any thought?

Thanks for reading.


Whenever you connect an external drive to your mac, the storage drive may not show up on Desktop, Finder, or even on Disk Utility due to various reasons:

  1. USB connectivity problem
  2. macOS preference settings
  3. Partition map damage
  4. Device incompatibility
  5. Physical damage on a drive
