[QUOTE=Dsp121;2454133]I have found posts in this forum saying that LiteOn DVD-RW drives only report E31 errors. Does anyone know for sure and can confirm this, please? [/QUOTE] Only people with inside knowledge can know “for sure” and they are silent on the subject.
The rest of us can deduce from observations with a high certainty, that the LiteOn DVD burners, at least the ones I have used, report only E31 as C1 and E32 as C2 when using KProbe or CDSpeed.
This means that only the gravest C1 and C2 errors are reported, which paints a prettier picture than drives that report all errors.
That means these drives are unsuited for quality scanning CD-R media, but they can be used in the sense that a bad scan is definitely a sign of a bad disc, while a good scan doesn’t mean much.
