[qanda]This thread is about the Samsung SH-S203P / TS-H653P. Click here to see full specs[/qanda]Hi!

I just burned an ISO image to a CD-RW media, that is not the newest, using a Samsung SH-S203P SB01 unit using CDSpeed 4.11.2

Then I did a Disc Quality test and got suspiciously low amount of C1 errors. Almost al CD-R media has constantly C1 errors (even if low amount), while my disc had mostly zero C1 errors.

Mediatek chips (liteon & Samsung) are not good for cd scanning, nec chipset are OK for cd’s and the best is a true plextor & benq.

So is this normal ? Or an error in testing ?

The result looks ok, since it’s scanned with mediatek based drive.

Doesn’t an uncorrectable C1 error create a C2 error ?
Or am I misunderstanding it ?

[quote=xerces8;2133621]Doesn’t an uncorrectable C1 error create a C2 error ?
Or am I misunderstanding it ?[/quote] Yes, an uncorrectable C1 error (E31) results in several C2 errors (E12, E22 or E32).

However, most uncorrectable C1 (E31) result in correctable C2 errors (E12, E22) and are thus not [U]un[/U]correctable C2 errors (E32).

Only the [U]un[/U]correctable C2 errors (E32) are reported as C2 by the Samsung and most other scanning drives.
