The Optorite DD0203 gets a good score of 75.1 out of 100 at the error correction tests. The drive gave back many read errors with the scratched disc, but behaved very well while reading the defected disc.
- CDSpeed Quality Test
Optorite DD0203 does not retrieve C2 error information accurately, at least at the maximum reading speed. For this reason, the Nero CDSpeed quality test could not give reliable information about the error correction behavior of the drive, resulting to the score given above.
