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: 891594
Errors (Loudness) dB(A)	Num: 43631	Avg: -72.3 dB(A)	Max: -21.6 dB(A)
Error Muting Samples	Num: 6018	Avg: 2.3 Samples	Max: 612 Samples
Skips Samples	Num: 0	Avg: 0.0 Samples	Max: 0 Samples
Total Test Result	75.5 points (out of 100.0 maximum)
C2 Accuracy	99.5 %

Toshiba displayed rather good performance with the specific test disc. The total error count can be characterized as lower than average, (which is good), while the maximum error loudness level is also relatively low although still over the limit. There were no skipped samples and according to our experience, 75.5 points out of 100 is a good score for this test.

- ABEX TCD-726

Errors total	Num: 12
Errors (Loudness) dB(A)	Num: 4	Avg: -89.9 dB(A)	Max: -71.0 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	94.1 points (out of 100.0 maximum)
C2 Accuracy	99.5 %

The Abex TCD-726 test disc is much easier for drives in general to read. The spike at the beginning of the test is not high, however it deprived the drive of a perfect score.

- 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 (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.

Error Level	1	2	3	4	5
Toshiba SD-R5372	5/5	5/5	5/5	5/5	0/5

The drive successfully passed four out of the five check levels for this test. This is very good performance since an average drive manages to play up to the third level while very few drives manage to read the fifth.

- Summary

CD error correction on the SD-R5372 drive is quite good.
