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)?
