LIMITED WARRANTY! WD has re-certified these as new & sealed them in plastic bagging. No retail packaging, no retail box like the 3D rendered default pic. Why pay $100+ extra just for fancy fluff that you just throw away? Guaranteed that the item you receive is in 100% working order, or send it back to us for a replacement within 30 days. Your satisfaction is 100% guaranteed. From WD "Recertified means that products are returned for whatever reason and then run through the full set of quality tests that new products go through. If any test fails, the product is scrapped and recycled. Normally, if there is something wrong with a product, it will fail within the first few days." So a limited warranty is all you really need. Warranties that are for 1+ years or paying for extended warranties are usually unnecessary because if a drive is going to fail, you will know it within a week.
