August 30, 201510 yr Just purchased a new WD REd 4TB drive and ran it through 2 preclears. Does the drive look bad?

August 30, 201510 yr I think it has to fail WDs tool first before they allow an RMA. Return if you can. Once, I accidentally rapped a drive on the table while it was plugged in, and it definitely did not help its health. In fact, WDs tool couldnt even see it. Moral of the story is, I need to be more careful.
