Question: When trying to write a CDR/RW, why do I keep getting a Power Calibration error? Answer: "The error indicates that the CDR/RW drive is having trouble calibrating the power setting. The power setting of the laser in a CDR/RW is between 4 and 8 mill watts. CDR/RW discs have a section outside the standard recording area called the Program Calibration Area (PCA), which is used to adjust the laser for the brand of media you are using. Try using higher quality brands of CDR/RW discs, and if that doesn?t work you should have the drive repaired or replaced. "
