1.cleaning the lens is one option that didn't rectified 2.disabling IMAPI didn't rectified 3.reducing writing speed does not rectified all done with best quality cds.please suggest me.to my mailaddress
What model drive, what firmware, and what speed ratings for the CD-RWs? There are three speed classes: 1-4X, 4-12X high speed, and 16-32X ultra speed. All CD-RW drives can record the first class; high-speed drives can record two classes; and ultra-speed drives can record all three speed classes, but not necessarily every disc in every class.
DVD's and Cd-r disks themselves have information written on them, within this Media ID code there is information that the drive uses to calibrate itself to the disk. When a drive first starts to write to a disk it will burn a small amount of data to a calibration area on the disc. Using the calibration information in the Media ID code it tries to read back the data that it has written. If it cannot be read, then disk will be ejected and fail with a power calibration error. To resolve this update your firmware to the newest available.
