First of all I never said that(see my post), second the fact is not entirely wrong. "WD only provides re-certified drives for their non-5 years warranty models as default replacement policy"."Thanks whitestar for making aware that WD only provides refurbished drives" - this is factually wrong.
P.S. I don't understand why are you defending WD so much, I am not some newbie who bought a hdd & then complaining why I did not get 4TB space in a 4TB hdd or why hdd is not working at 120MB/s all the time for all file transfers incl thousands of small few mb files. I have presented all the technical details. WD is selling a model in India which can easily reach 60C in winter season & then they are offering a re-certified drive as replacement, case closed.
