Performance in Nero CD-DVD Speed: Advanced DAE Error Correction Test

To check out the ability of the drives to process errors occurring during extraction of audio tracks I used the specialized Advanced DAE Error Correction Test with the same bad compact disc prepared by Nero CD-DVD Speed. The test utility determines how many C2 errors should be found by the drive and how many it does find, producing Quality Score and C2 Accuracy parameters which reflect the efficiency of the hardware error correction mechanism of the optical drive.

Sony DW-D22A

Unfortunately, there?re no quality scores in the first two screenshots that belong to the LG drives: they just fell into a permanent coma at the same sections of the disc. Anyway, the screenshots indicate that the drives fail the test as they fail to find quite a number of errors. You can?t hope to get accurate audio copies with such results. The Sony DW-D22A has much better results, almost reaching the best possible result.
