my solution so far
I just bought the latest Robbie Williams cd(Escapology),and wanted to rip it to my portable mp3 player.The problem was the copyprotection.When I used CloneCd,all the tracks had an error after 9-10 sec.The solution was simple:Take a small piece of tape,paint it black with a pen,cover a small part of the datatatrack on the end of the cd with the piece of tape,and then use CloneCd.The copy was perfect,and I was able to rip the tracks to mp3 without any errors.The datatrack contaning the copyprotection is visible as a blank track close to the edge of the cd.I don't know why the errors occured,byt it worked out fine.I also tried Plextools and some other programs,but they could't read the cd at all,or made the same crappy copy.
I use a Plextor 40x,and it's the first time i've had these kind of problems making copys of my legally bought cd's.
