Yes autoplay was off and i started
clonecd before inserting the disc. I used the audio profile with "first session only" and my firmware is 1.13. It's quite a pitty i don't remember where i read that someone had the same experience. Maybe it's on cdfreaks.
I don't have any explanation. Anyway, i did the job with my writer and EAC.
If you have an ultraplex, you know it's possible to make an image of the audio disk (pxi) withe cd copy in Plextools. But i don't have a plextor writer. Do you know a way (= a software) to burn a pwi image without a plextor writer ?
