Hi I bought WD Essentials 1TB and it worked fine until I used wrong power supply (from netbook) and it stopped working. I opened the black case and found WD Cavier Green SATA drive. I took it out and bought IOMAX usb connecter for sata and pata. I tested first with PATA drive and it worked fine but when I connected WD Cavier drive (taken out from WD essentials) the power supply just turn itself off for no reason. can someone help?
It sounds like you damaged the the hard drive by using the wrong power supply.
All I can suggest is either testing another SATA drive in your new dock and if it behaves how you would expect, then it sounds like the drive has gone faulty.
