I had a similar problem late last year.  My new power supply (5 months 
old) in my desktop wasn't putting out the correct voltage on the +5V 
rail.  The drive would click and then stop.  As it was one of the RAID 1 
drives, this was causing me some headaches.  Any drive tests showed the 
drive to be okay.  Changing the power supply fixed the issue.  Did a 
full drive test on the drive before putting it back in.  No issues 
showed up.

If you can, check the power supply voltages.
