Do any other Mac Pro owners here (that have a stock DVD drive) have a loud drive? I'm trying to watch a movie and it's very noticeable over the movie's audio. It's pretty annoying and not what I would hope for in a $3000 machine, y'know? Yeah, I could buy a new one, but I don't need to...so for now I just want to know if this is pretty normal. And it sounds more like fans than something spinning really fast...but I could be wrong on that.
