Yamaha 8424ez

I have a terrible problem with my writer.
i use a yamaha 8424ez writer
and nero 5.1.8 (i tried changing the program and the OS)
windows 2000 sp2
my problem is that i cannot write to CDRW, actually the burn process is done perfectly but the cd is blank after that.
i use Sony RWs made by Mitsubishi Chem.

and I’m wondering if somebody can help me to find a way to solve this,

In win2k you need an apropiate ASPI32.dll
You can dl at roxio or ahead

i do have the approporite ASPI layer and i tried using windows Me and 98 also i tried to use adaptec easy cd creator and winoncd pro 3.7
