You need a drive that can read C1/C2 error information off a disc you've burned and then use a program to report errors (CD Doctor 1.04 is a decent application).
Unfortunately CD Doctro currently supports LiteOn/Samsung drives:
There will be an upcoming version of cd speed (keep checking at www.cdspeed2000.com
) that should support C1/C2 error checking. We don't know yet what drives it will support.
Until then, your choices are pretty limited and I can't suggest you any good way to measure media quality with your LG drive.
Can somebody else help out?
PS I bought a LiteOn 48246s on a discount just so that I can use it to check C1/C2 errors... I don't even use it for burning (at least, not yet).
