I recently purchased the legal game entitled Madden NFL 2006(USA) and I can confirm the Plexy PX-712SA makes a true 1:1 backup. The problem is A Ray Scanner can't determine the exact Safedisc cd protection unless I'm doing something wrong.
Settings I used to make a successful 1:1 backup
Read at 4x(Used Plexy as reader)
Burn at 4x(RAO DAO)
Backup plays in my Litey flawlessy
