All data gone on My Book Studio II

I’m another pissed off WD user.

I have just lost 10TB of data. All the contents of a 6TB WD and a 4TB Seagate drives have been wiped out. Both HDs have been renamed “MyBook”.

I’m not sure if I should wait for a solution from Apple or WD or if I should start trying to recover the data with Data Rescue or Disk Drill. Any thoughts?

Thanks.
