In the following tests, we check the drive's behavior when it comes to reading scratched / defective discs. The test discs we use are the ABEX series from ALMEDIO.

- ABEX TCD-721R

Good performance was reported while testing the drive with the 721 test media. The total error count is average while most importantly, no samples were skipped. Although the maximum error loudness is at -23.1 dB(A), if we take a look at the graph above, we will see that this was a single case while for the rest, the level remained below -36.0 dB(A).

- ABEX TCD-726

Flawless reading with the 726 test media. 100 points in total test result and 100% C2 accuracy.

- 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 ability to read music and reproduce it completely. Five tracks on the disc contain a sequence of progressively difficult tests. These tracks are referred as Check Level -1 through Check Level -5.

The tracks are reproduced (played) through a software multimedia player (i.e. Windows Media Player). Each level is considered as passed, if the tone coming out from the speakers is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested device.

Average performance in this case, with the CD-Check Audio Test Disc. The drive managed to read up to the 3rd error level. In the 4th level, audible clicks were present and the drive could not reproduce the track correctly.

Overall, good CD error correction capabilities.
