 The spot is clearly visible AFTER the burn (then it looks like the
 whole disk does before the burn). But not visible before the burn
 (and that is a bit sad, since I can pick out the bad ones before)

 Strange thing is that a test read (PIE) shows no more errors than on
 the rest of the disk (no peaks) and a verify show no errors either. Is
 the error correction/redundancy so good that it handles a 1 mm spot)?
