I'm not sure where he got it from, it may even have been a gift - he's had it some years.

I do appreciate you trying to help and I'm sorry for the lack of info, but I'm getting the driver repaired anyway and  I thought this would be a good opportunity to work on my SE/refunding skills as I've actually got the driver if they ask for any photos etc. Its just the problem of warranty and receipt of purchase I'm worried about.

That's fine, no need to apologize.

Part of SEing Is knowing the Inner-workings of the company, Inclusive of their terms and In particular their refund/replacement policy. Exploiting the human firewall (social engineering), takes effect thereafter. Without any knowledge of the company per se, you cannot Initiate a starting point.

I'll do some research before hand then and look for any cases online where people have had their broken drivers replaced and how they went about this.
