Laserlock Marathon (or Laserlock Star) is a totally different type of copy protection to that of earlier versions of laserlock (just as securom v. 4.77.0050+ uses a completely different copy protection scheme to that used by all previous versions of securom).
Whilst CloneCD arguably was the best application for copying cds with older forms of laserlock, it cannot successfully copy a cd protected with Laerlock Marathon.
To copy a Laserlock Marathon protected cd you will need to use alcohol with slightly modified securom new 4.x/5.x/7.x (not securom or securom new) settings as it uses a similar protection scheme but with the nasty addition of a cut ring near the outer part of the disc.
As stated, to make an image of the disc, use securom new 4.x/5.x/7.x settings but check also Advanced Sector Scanning and set the ASS jump factor either to 100 or even to 500.
The image should run when mounted to a virtual drive. If not, then try with YASU activated to overcome blacklisting problems.
If you want a physical back-up, burn the image using standard securom new 4.x/5.x/7.x settings and remember to enable RMPS emulation in alcohol's emulation options before attempting to run the physical back-up copy.
