Error Correction Tests

In the following tests we examine the error correction capabilities of the MSI MS-8152.

- EAC CD-R Test Disc

- Test Results (Max Reading)

Errors total	Num: 466139
Errors (Loudness) dB(A)	Num: 16452	Avg: -64.7 dB(A)	Max: -7.7 dB(A)
Error Muting Samples	Num: 504	Avg: 7.8 Samples	Max: 569 Samples
Skips Samples	Num: 0	Avg: 0 Samples	Max: 0 Samples
Total Test Result	77.8 points (of 100.0 maximum)

The errors within the black triangle defect reached -7.7dB in specific areas and gave an average of -64.7dB(A). The five scratches also produced errors of the same approximately level. The score is 77.8 out of 100 (max), which is considered as average for a CD-ROM drive.

- ABEX TCD-721R

- Test Results (Max speed)

Errors total	Num: 1641090
Errors (Loudness) dB(A)	Num: 71562	Avg: -69.9 dB(A)	Max:-8.0 dB(A)
Error Muting Samples	Num: 4980	Avg: 1.9 Samples	Max: 563 Samples
Skips Samples	Num: 0	Avg: 0 Samples	Max: 0 Samples
Total Test Result	75.4 points (of 100.0 maximum)

The score with the TCD-721R test disc was 75.4. The drive didn't skip any sample, and but gave many muted samples, while it kept the average error rate at -69.9 dB(A).

- ABEX TCD-726

- Test Results (Max Speed)

Errors total	Num: 29223162
Errors (Loudness) dB(A)	Num: 146544	Avg:-28.7 dB(A)	Max:-6.4 dB(A)
Error Muting Samples	Num: 150231	Avg: 45.7 Samples	Max: 3584 Samples
Skips Samples	Num: 10	Avg: 792.7 Samples	Max: 2939 Samples
Total Test Result	51.1 points (of 100.0 maximum)

The drive didn't perform very well with the TCD-726 test disc. The problem is that the defects and fingerprints caused many errors and muting samples. As it seems the drive cannot handle well defects and fingerprints. The total score for the test is 51.1 points out of 100 (max).

- Conclusion

Test Disc	Reading Speed	Score
EAC CD-R	Max	77.8
ABEX TCD-721R		75.4
ABEX TCD-726		51.1
Average Score		62.56

The MSI MS-8152 gets an average score of 68.10 out of 100 in the reading error correction tests.

- C2 Information accuracy

- Tests Results (Max Speed)

The drive gave a 99.81% C2 accuracy with the ABEX TCD-721R test disc and an 81.9 quality score. The EAC C2 % accuracy results are not different with the EAC CD-R and the ABEX TCD-726 test discs.

Test Disc	Reading Speed	Score (%)
EAC CD-R	Max	99.7
ABEX TCD-721R		99.7
ABEX TCD-726		62.9
Average Score		87.43
