It is unusual to see a drive register so many errors with this test disc. The Total Test Result score of 79.2 is a little disappointing.
- 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 (e.g.
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.

- Summary
Overall, the drive is not very good with faulty CD media. Apart from the TCD 721-R disc, its performance was below average.
