I changed my HDD on my slim PS3 like 3 weeks ago. I upgraded it to 1tb also as the OP is trying to do.
To the OP, I would try taking the HDD back to where you bought it from. If that doesn't help I would call Sony and explain the situation to them and give them the error code. Also trying downloading the latest firmware and updating it via USB via the recovery menu.
