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 then produces C2 Accuracy and Quality Score parameters which reflect the efficiency of the hardware error-correction logic in the given 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 screenshots show that the efficiency of the hardware error-correction of the Pioneer DVR-110D is rather low. It can only find about two out of each three C2 errors. This is obviously not enough to process a scratched disc normally. The Toshiba SD-R5472, on the contrary, has an almost ideal percentage of found C2 errors. So, you understand what drive wins this test.
