InCD is packet writing, and that's know to be problematic, unstable, prone to data error and loss.
some people have great experience with it, some terrible.
i recommend you do "regular burning" with NeroExpress, and full-erase the CDRW when you're done with it and want to re-use it.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the land of Mordor, where the Shadows lie
