Strange CD-RW problem

Its really strange problem, i got a verbatim cd-rw that isn’t allright, always damaged sectors in the beginning, so sometimes i let scan-disk from nero do a “surface scan”.

Now i burned a Phillips CD-RW (4x-12x) as an audio disk, and when trying to scan, it only says error, when i looked at the cd-rw i saw a dark part on the surface, so i thought the cd was defect,
but after burning a second cd-rw from Phillips, from a different series ( 4x-10x ), i also got the error when trying to scan the surface.

All my other CD-RW’s ( Intenso, LiteON, Verbatim ) and the cd’s from Phillips are scanned without problem.

Does anybody else konw the problem ?
