During testing of some new burners I noticed a big difference in KProbe scans.
This one comes from LDW-451S:
And this from combo drive LTC-48161H (really, it's the same medium!):
Burnt with LDW-451S/GSB6 on a fresh 4x DVD+RW (Verbatim, Code MKM A02).
Why is the scan result SO different and which tells more the truth about the quality of burning?
