I made partially working CDs backup with Clone CD. With Alcohol 120% and its RMPS function, I was able to create fully working backups of CD-COPS v1.81 and CD-COPS v1.74 protected CDs.
-read subchannel data
-Data Position mesurement (DPM): high precision
-Burn RMPS to media
In the Alcohol 120% Emulation settings, be sure to select the “RMPS” setting.
I am using normal cheap under 50cents 700megs media.
I have a recent LG DVD-CDRW drive
The mounted image also works!
Thanks eveyone for your help.
I hope this will help other people
