In the following tests we check the drive's behaviour when reading
scratched / defective audio discs. The test discs used were the ABEX series
from ALMEDIO.

A fairly decent effort with the specific disc. The total error count is not too high while the maximum error loudness is rather good and very importantly, no samples were skipped. The good performance is rewarded with a good Test Result score of 76.5.

The ABEX TCD-726 test disc is always easier to read but we did not expect it to be that easy!. No skipped samples and no error muting samples indicate excellent performance.
- 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 (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.

With this test disc, the drive reported average performance, achieving flawless
reading with 3 out of 5 tracks.
- Summary
Overall, Samsung seems to have rather good CD Error correction capabilities.
