Working on a forensic job. Need to determine WHEN a CD was copied with a disk copier similar to Easy CD creator. The standard tools that read ATIP info which unfortunately gives the date the CD was initially mastered. We are dealing with CD's that are copied, according to a quick experiment with a manufactured disk, the Content Date reported by Nero Info Tool is the same value on a copy and original. Where to look for hidden information about when the copy was done?
