I am experiencing exactly the same issue. I only have two shares on the drive both of which have media turned off. Ever since changing to RAID 1 and copying about 1TB to the drive (which took 1.5 days over gigabit - ridiculous), it is always blinking and you can hear the heads clicking constantly.
I then tried to shut down and restart and then tried turning off any device that would access it. Keeps working hard. I updated the firmware and thought letting the hard drive finish its indexing would change that but a day later, still working hard.
I also tried to submit a ticket to WD but their support links all give an error. Anyone have any other ideas? :) Thanks!
