These screenshots show you the results of the DVD+RW quality check test. By the way, you can note that the TDK disc is made by Philips, and the Fujifilm disc is actually produced by Ricoh. The GSA-4082B has the smallest number of PI Failures, although has only the second place in the quality score (well, it’s not quite correct to make direct comparisons with the other drives, as discs from different manufacturers were used with them). The GSA-4160B has got the highest quality score – having made few PI errors as well as PI Failures. The quality score of the disc produced by the Sony DW-D22A is zero – too many PI Errors and Failures.

The three last screenshots show you the quality of the molded disc with scratches. The LG GSA-4160B is the only device here to have a quality score other than zero. The Sony DW-D22A has the most errors here, but it worked at a higher speed and, as we learned earlier, it finds a higher percentage of C2 errors.
