Ok so I have a 500GB WD "Blue Scorpion" HDD that I'm trying to access via USB, when I boot up my CentOS laptop the lights on the external USB casing light up...and I can hear the drive making noise, but after a few minutes I hear an abrupt "click" and the drive doesn't do anything. I can SEE it in the Disk Utility in CentOS,...I even tried to format it from there as well and the symptoms are still the same. The lights come on...it looks like its about to do something...and then the loud click and nothing happens. Can anyone volunteer some advice as to where I would look for troubleshooting this issue? I really am not interested in what's on it. I just want to re-format it and (possibly) use it for storage. I have tried using various toosl to try and wipe this drive but nothing seems to work...(SystemRescue CD....D.B.A.N.......PartImage....Hiram's BootCD....) Any help or advice would be greatly appreciated. Thanks In Advance EGO II
