Actually, without overburn enabled it should refuse to even burn at all if it is a media size issue. Yes, it is a mystery. My guesses as to what it will end up being, in order of most to least likely, are
  • 1 Media related
    2 A burner issue, such as a dirty lense (or just a bad unit, since you say it is new).
    3 Something nasty that has infected your Windows system
    4 As a last desperate guess I would say something USB2 related. I don't really believe that, but I don't think USB should be used for burning media either. And you say it is a USB2 drive - you do have it on a USE2 interface and not an old USB 1.1 interface, right?

I'm really at a loss to understand the overwriting failed error message; I've burnt lots of CDs and DVDs with Nero 6, have made more than my fair share of coasters and had read errors during the verification pass many times, but I've never seen a overwriting failed error.
