How are the drives connected: individually or RAID? Are you trying to boot from one or both? I have to mention that WD recommends that Green drives be used as secondary or data drives. If these are not the boot drives, will the system boot with them disconnected?
Search for a “Hiren’s bootCD” ISO image online. It contains many recovery tools which might help you in this situation.
Hi you need to get the Wd data lifeguard tools for dos put it on a cd and boot from it. Then run a test on the drives do one plugged in at a time, if and I imagine they will come up with errors. Go to this page to run a warranty check and start your RMA. This is to check warranty and start RMA  http://support.wdc.com/warranty/index_end.asp?lang=en .
