Support, for an upgrade I performed myself?

Yes. The worst they can do is say "no". And somehow, for someone who's been around as long as you have (for those who don't know, Doug316 sold me my first Mark1 which I still have), I would imagine they'd be happy to help you. Especially if the problem was unrelated to your drive upgrade (and I imagine it is probably unrelated to your upgrade as long as you were careful).
