This drive is a time-bomb waiting to explode data all over the place. Get on the phone with WD and get these drives replaced immediately. Don't waste your time working on them. The old Hitachi/IBM 'Deathstars' would exhibit the same behavior shortly before they died. As I said, now it the time not to hope you have a viable backup of your important data as you will be exercising it soon.
