Warning! Apple Mavericks is corrupting external hard drives - wiping them clean and reformatting them with little warning. There is currently no solution. My 3TB Seagate music server is gone. Reformatted as MyBook and EFI partitions.
WD not the only drives affected, although I did have the WD Drive Manager software on my affected Mac Mini - could this be the culprit?
