In the following tests, we check the drive's behavior when reading scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

- ABEX TCD-721R

Errors total Num: 682347
Errors (Loudness) dB(A) Num: 39691 Avg: -73.1 dB(A) Max: -19.6 dB(A)
Error Muting Samples Num: 2258 Avg: 1.0 Samples Max: 7 Samples
Skips Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
Total Test Result 77.4 points (out of 100.0 maximum)
C2 Accuracy 99.6 %

Looking at the above graph and table, the error correction of the DW-G120A with the specific test disc quite good. The total error count is low. There are a couple of spikes with the maximum reaching -19.6 dB(A) but this wasn't enough to produce any skipped samples. The total test result score is a bit better than average. However, the C2 accuracy score is very good.

- ABEX TCD-726

Errors total Num: 0
Errors (Loudness) dB(A) Num: 0 Avg: -174.0 dB(A) Max: -174.0 dB(A)
Error Muting Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
Skips Samples Num: 0 Avg: 0.0 Samples Max: 0 Samples
Total Test Result 100.0 points (out of 100.0 maximum)
C2 Accuracy 100.0 %

Most drives can read the specific disc without any errors and fortunately the Sony is one of them.

- CD-Check Audio Test Disc

The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction / Error correction capabilities of a CD player. The disc offers a signal combination with disc error patterns to rate the drive's abilities to read music and reproduce it completely. Five tracks on the disc contain a sequence of progressively more difficult tests. These tracks are referred to as Check Level-1 through Check Level-5.

The tracks are reproduced through a software multimedia player (e.g. Windows Media Player). Each level is considered as passed, if the tone is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested drive.

Error Level 1 2 3 4 5
Sony DW-G120A 5/5 5/5 5/5 0/5 0/5

With this test disc, the drive reported average performance, achieving flawless reading for 3 out of 5 tracks.

- Summary

Overall, the Sony drive offers average to good CD Error correction capabilities.
