Which is more accurate? Copying an entire CD using an IMAGE copier or using correctly set up EAC track by track?
The question should be “which is more secure?” because both can be accurate - this depends on the drive and the condition of the disc that you’re going to read. EAC probably will be better since it offers several techniques to detect occured errors. Besides that, with EAC you aren’t stuck with reading track by track but can read the entire disc at once.
