[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.
