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 maximun error loudness is quite good.

- ABEX TCD-726

This is about average performance with both the Abex TCD-721R and TCD-726 test discs.

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

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

The drive managed to playback the first three levels of the audio check disc without problem. The drive played back the three tracks without audible clicks while it found it hard to pass the last two error correction levels. Again, average performance.

- Summary

The Asus DRW-804P received an average score of 84.55 points out of 100 with the two Abex test discs.
