Nero CD-DVD Speed: Advanced DAE Error Correction Test
We ran the Advanced DAE Error Correction test with the bad audio CD prepared in Nero CD-DVD Speed to check the drives’ ability to process errors that occur during the audio ripping process. The program determines how many C2 errors should be found by the drive and how many errors the drive actually finds and produces C2 Accuracy and Quality Score parameters which reflect the efficiency of the hardware error-correction logic in the optical drive. Unlike the previous test, this one not only tells how many errors occur as the drive is reading an audio CD, but also evaluates the drive’s ability to find such errors.
The number of missed C2 errors is quite high with the ASUS DVD-E616P3, and the drive’s accuracy at finding such errors as the program calculates it, is rather dubious if you examine the numbers carefully. The Plextor PX-130A looks even worse than the ASUS in this test. Its calculated C2 Accuracy is less than 1%, but it’s not quite clear how the program arrives at this value with the given number of missed and found errors. The Sony DDU1615 shows good skills at finding C2 errors, even though it doesn’t reach a 100% quality score. The other drive from Sony, DDU1622, performs no worse than the DDU1615 in this test. The Toshiba SD-M2012 fails this test completely as it can find not a single C2 error at all.
