I had read that the Samsung drives don’t report C2 errors, both in the FAQ and in some posts around. This seemed to include the 203B.
Also, when scanning some slightly scratched CDs with it, no C2 errors appeared in CDSpeed though the discs scanned were reported by my other drives as having some C2 errors.
Nevertheless, as EAC declares that it does report C2, I digged the matter a little deeper.
After having thoroughly checked this drive as a ripper in secure mode with EAC (C2 feature enabled), with numerous “test & copy” with the aforementioned CDs and some additional heavily damaged CDs, I could safely assume it reported C2 100% accurately with this software. No reading error whatsoever was skipped, all were corrected, all CRCs matched and this was checked against Accuraterip.
So I scanned one of the heavily scratched CDs. Hello C2 reporting (see posted scan).
My conclusion is that the 203B is one of the very best CD readers around. It does reports C2 accurately, but it’s so good a reader that it can show C2-less scans with marginal discs that other scanners will declare bad, with several C2 errors. I have no idea if this is due to the quality of the optics, an outstanding error correction algorithm, whatever, it’s impressive, and a litle confusing.
So the 203B can still be considered, IMO, as an unreliable CD scanner, because no C2 in a CD scan with the 203B doesn’t necessarily mean that the disc is in good condition, though the scan is actually accurate!
On the other hand, as a CD ripper, it’s certainly one of the best choices for people who rip damaged CDs. - it beats all of my other drives in this area.
