you could have removed the hdd, copied it externally, reinstalled it and send it. But you were clever... per human standards, not business.
corporations are stupid, they can't be any different. consumer rights are constantly broken. I have had 3 dead asus rog boards, lost all my money, because they invent reasons to ignore your right to warrany. There are better ways to deal with customers. I'd say, keep all their stoopid boxes and included items, and return their products at the slightest issue first day. Make them pay for it.
