LaserLock Tests
This type of CD stores its protection in the MainChannel data from the CD; therefore only options regarding error handling are useful in order to create a safety backup. Usually it has over 6300 bad sectors, which must be read.

Most of the drives we have tested make a LOT of time reading the original CD. Especially the Plextor drives are not the best choise for reading LaserLock protected CDs. When we say not best choise it means that the Plextor drives are SLOW when using them for reading the original CD compared to other drives. However things are not the same with the backuped LaserLock protected CD. It seems that all drives read it much faster than the original one. Below are some results using various LaserLock protected CDs and various drives (bigger is better) using both Fast Skip Error and Intelligent Bad Scanner ticked options:

Conclusion:
There are huge differences in time when reading the original and the backup LaserLock protected CD. From our tests the best settings for both Original CD are to tick both the "Intelligent bad sector scanner" and the "Fast skip error". On the other hand the best setting for Backup CD is the "Fast skip error" only.
