Ok all of a sudden yesterday my Wii (D2B, circa Christmas 2006, modded with WiiFree and later with OpenWii) DVD drive got REAL loud. Vibrational, sounds like it's vibrating the whole case. Buzzes, if you will. Games still load and run fine. I have never bothered to change defaults, so for all I know OpenWii has been overdriving it... What are my basic steps in troubleshooting here? I haven't even cracked it back open yet, but assuming I rule out "oh hey look a loose screw", what's next? If it comes down to it, can I get a D2B replacement drive (for any reasonable price, I've seen drives for $150 which seems silly on a $250 unit)?
