Some weird audio CD protection...
 
Hi guys,I've been trying to copy an audio CD but I have been unsuccesful so far. It's a legally bought CD with a warning on its case saying:"This product contains copy protection.Copying to PC/Mac is not possible."I've tried copying it with Clone CD but the copy didn't work.My Sony discman couldn't read tracks.It reads tracks of the original CD normally.This is what various info tools say about this CD:

I've tried to copy it on the fly using CloneCD with settings taken from ClonyXL
(for CD extra),but that also didn't work.I'm really confused.Do you have any suggestions? :suspic:

Connect your stereo sytem to your PC via the Line In on your sound card then use some recording software and save the tracks to HDD. After that it's just a case of burning the tracks to CD.

Normal players just blindly read the first session of a CD, beginning to end, while computers read and combine all the session info, so adding corrupt data sessions to the end of an audio cd acts as a basic protection scheme. You need to either use a tool like Plextools Pro if you have a plextor and enable Single Session reading to make it ignore the extra session info at the end of the disc. I don't know of any other tools for different brands of CD/RW.

You could try using CDRWin to make an image of the disc then edit the .cue file and burn back without the data tracks?

There is also a theory, which I've never tried, that you can get a marker pen and draw a circle around the outside edge of the CD, which your CD-Rom will just see as faulty data and be ignored completely, bypassing the corrupt session info and making the CD copyable.

Has anyone tried this?

Use CDRWIN
Read TOC (table of contents) & print. A error message will appear "can not read from sector [U]xxxx[/U] to yyyy" take note of the sector number "from".
Go to "Extract Disc\Track\sector.
tick "Select Sectors" at "Select Selection" you have "Start & End"
From Your Print Out
Track 01 put your start sector, the end sector is the start of track 02
Track 02 put your start sector, the end sector is the start of track 03
and so on. Remember to save tracks as 01, 02, 03, and so on.
The last Audio "end " sector is the "From" sector in your error message.
This method also works with same copy protected CDG discs but remember to change the drop down box to CDG.
Then go to "Record Disc" "Load Tracks" Audio or CDG and burn.
