Difficulty writing to optical media
1. Verify the correct type of disc is being used.
2. Try a different brand or speed of CD-R disc.
Note: Some brands of 24x or 32x CD-R media may not work with the SuperDrive.
Note: There are two factors in the ability for the optical drive to write to media. First, there
are varying qualities of blank optical media. Some media are made to such low
specifications that the ability for the drive to write to it is marginal.
There are variations in optical media even under the same brand. Some brands source
their optical media from a variety of manufacturers, so there may be variations in the
quality.
Second, an optical drive that supports writing to a CD-R/RW or DVD-R/RW disc requires a
special writing algorithm for discs from different disc manufacturers. There are hundreds of
disc manufacturers, it is impossible to implement writing algorithms for each disc
manufacturer. Usually, drive manufacturers implement special writing algorithms for discs
from major disc manufacturers. For discs that are not supported by the drive with special
writing algorithms, the drive will use a generic writing algorithm to write the disc. In this
case, the writability and readability may not be optimal.
3. Replace optical drive flex cable.
4. Replace optical drive.
