Same disc scanned on different drives, very different results

The disc is a Ricohjpn R02 burned @ 12x.
Scanned with my 1620, then with my LiteOn 832s.
My question is, which scan should I believe? :confused:

Though they say not to scan with different drives, I would have to go with the Lite On as it is a ECC 1 scan at least for the PIF. More accurate from what I have read from the experts opinions.:slight_smile:
