Troubles with WD "Recertified" Caviar Blue HD's

Hello - They were all used in a Cooler Master computer case(HAF X Nvidia Edition) high air flow series, that I bought while working over in England.  That case is in the theater room and in a room off to the side with all the audio, video, gaming & other components that I have, and that room is air conditioned and kept at 72 degrees all the time - so nothing get’s hot or over heats. I did what you suggested with 2 of the 500GB HD’s but to no luck using the WD program, you can slowly spin/twist(like your winding a Seiko Automatic watch) the others and you hear nothing spinning inside. Thanks for your help & for trying and get me out of this jam, I’ll buy only “NEW” from now on - I’ve learned my lesion with seconds, refurb’s or someone else’s turned in HD I guess.
