23. Conclusion
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.

The total error count is very high, however the maximum error loudness is within acceptable levels, according to our experience. Although the muted samples count is also somewhat high, there were no skipped samples. The total test result score of 74.9 is quite good.

This is a much easier test disk than the previous one and most drives pass this test with a near perfect score, something that the 4167B didn't do. The total test result score of 79.7 out of 100 is not as good as it could have been.
- 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 being reproduced through a software multimedia player (i.e. 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.

The drive successfully passed only the first two out of the five check levels for this test. This is not good performance. Almost all drives have difficulties reading the 5th level, while a good drive can read the 4th level. But almost all drives can handle the third level without any problems. This is similar to the previous LG model, the GSA-4163B and is considered below average performance.
- Summary
CD error correction with the LG GSA-4167B can be described as mediocre.
