Summary: We had some of these drives from our Amazon wishlist. We received all the drives, but noticed some of them labelled with HP labels. One of the drives was DOA, another drive was showing that it had been used previously. The drives did NOT arrive with receipts, so we can not return them or get parts replaced. We contacted Amazon, but without the gift receipt from the purchase we can not do anything with the drives. I can not emphasize that last part enough.
