I've tried to format CD_RW 74 4X-10X Philips via INCD 5.0.
But after some formatting, the error code (00aa-0003-0073-0003) is
displyed.

What's the problem?

Thank you for reading

The latest InCD version is 3.51.61; do you really have 5.0?

Your problem could be due to a poor match between your burner and the media you were using. For instance, if your burner can write CD-RW at 4x only, it can't handle High Speed media (4x-10x or 4x-12x). Further, some burners do not cooperate with CD-RW discs from certain vendors. Hence you should test several discs from different manufacturers.

Nobody will be able to help you if you don't provide detailed information about your hardware and software. To get an idea about what is required, read the recent threads on this forum. In particular, if you are running Win9x, see
