I have been using this WD external drive for backups since 2009. Today, it started making a clicking sound as it was powering up. The light comes on, the disk spins and this clicking sound repeats about 6 times at 10 second intervals. This clinking suggests that a mechanical part is trying to engage. A message eventually appears on the desktop - “The disk you inserted was not readable by this computer. Initialize Ignore Eject” (choose one).
I suspect a broken part. What is the likely source of this noise? And what is the possibility that the disk can be repaired OR that the data on it can be recovered?
I use it with 2 computers - MacBook (2.4 GHz Intel Core 2 Duo), OS 10.6.8 ; and iMac (3.06 GHz Intel Core 2 Duo), OS 10.6.8.
