Performance during Damaged CD-ROM Disc Reading

Our traditional check of the error-correction mechanism with a badly damaged CD-ROM concludes the ¤€D-related?part of the review.

BenQ DW1620

LG GSA-4160B

The new BenQ did a good job of reading the test disc, handling it in 3 minutes and 41 seconds, while the GSA-4160B took 6 minutes and 13 seconds or almost twice the time to do the same. The LG, however, made only two mistakes against four committed by the BenQ.

I wouldn£s say that the BenQ has a bad error-correction mechanism, though. Yes, it£r worse than that of the competitor, but is good by itself. The speed-up/down mechanism works well, so either the optics or the ECC restoration algorithms fail. And considering that discs like the test one seldom occur in real life I can claim the BenQ DW1620 to have a fast and quite accurate error correction. Users who often use very bad media may want to consider slower, but more accurate models, though, like the GSA-4160B from LG.
