That’s exactly what happened to me. Do you have someone higher up looking into it? I was told by Seagate that Newegg is one of their trusted sellers this should not happen. Seagate assured me they will get back to me. Whether that happens is still a mystery.

5 year manufacturer warranty listed on the sales page doesn’t equal OEM

That would normally be fine if it were Server Part Deals, who is familiar with drives and honors their own in-house warranty. Newegg won’t return a drive after their return period. This drive is sold and shipped by Newegg and is sold with 5 year manufacturer warranty. Not as an OEM drive. There’s no excuse for it.
