Ever since CloneCD version 3.2.1.1 and BlindWrite 1.1.0.7 IIRC, there has been a feature available that will amplify the sectors of the SD2 signature when burning. There were legal problems anticipated if this feature were to be released with CloneCD for sale in the US, so CloneCD checks your regional settings in Windows, and if they're set to US, the weak sector amplification is disabled. It's easy to work around this by setting the region to Canada or Zimbabwe though. Some people have changed their region and still have AW disabled, in this case you can search for 'CloneAMP' and use that, or try searching your registry for 'amplifyweak' and set it to 1. It works marvelously, as my Lite-On 16X could not back up SD2 without AW, and I backed up MOH:AA with AW just fine 🙂
