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

In general, Plextor produced satisfactory results in this test. Both the total errors as well as Max. Error loudness are high and there were 2 skipped samples.The overall test score of 70.4 points out of 100 is about average.

- ABEX TCD-726

The 726 disc was read flawlessly and the defects were not a problem for the PX-760A. Good performance from the Plextor drive here.

- 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.

The drive successfully passed 5 out 5 check levels for this test. Very few but the best drives are capable of reading the 5th level. The Plextor drive managed to read all the entire test disc without problems.

- Summary

Overall, the drive showed very good CD error correction capabilities, especially if we keep in mind the performance with the CD-Check Test Disc.
