Thanks for your advice. Unfortunately, I wasn't able to solve my problem. But I tried to format CD-MRWs some more times, and now there is an error message:
"Error writing on disk in H.. ..." (The original error message is german)
I deinstalled InCD and Nero and reinstalled them again, but with no effect.
I read somewhere that a conflict caused by some older drivers / cd-burning-software may result in this behaviour. I have no other software installed, but some time ago I used InCD 3.x (now deinstalled).
Any ideas how I could find out what drivers / software may cause conflicts ?
Any other ideas ?
