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.

Rather good performance was reported while testing the drive with the 721 test media. The total error count is very low while most of the errors (red in the graph above) are below -36.0 dB(A), with just two spikes reaching around -22.6 dB(A). No skipped samples were reported and the 77.4% total test result is good.

- 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.
