Error Correction Tests

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

The performance with this disc is good. The total error count wasn`t too high, and the maximum level of the loudness errors reported will probably mean audible "clicks" in playback. It gave us a high number of error muting samples but finally the total score is acceptable.

- ABEX TCD-726

The Abex TCD-726 test disc is much easier for drives in general to read. That's why CyberDrive performed better than with the previous CD. The total error count was not high, while there was one skip and no mutes. The total score of 83.6 out of 100 is good.

- 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 performed good. It managed to playback all of our attempts, except the fifth level.

- Summary

The total score of the drive is good having an average score 79,95.
