The performance with the 721R test disc is about average. The drive
reached a very high -9.6 dB(A) Error Loudness level and also skipped samples.
The drive cannot return C2
error
pointers, so there's no C2 Accuracy score.

The Abex TCD-726 test disc is much easier for drives in general to read. The
Pioneer DVR-108 drive reached 92.2 score (out of 100), a good score.
- 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.
