Why wont your CD burn it wont except all cds you try to use?

There could be several reasons your CD burner isn't accepting all CDs. It might be incompatible with certain types of discs, such as using a CD-RW when it only supports CD-R. Additionally, the drive could be malfunctioning, or the discs themselves might be damaged or of poor quality. Lastly, outdated or corrupted drivers could also prevent proper operation.
