Illegal Mode for Music CD

Recommended Posts

I was trying to create a clone of the CD, which had a fair number of light scratches, but nothing deep. I'd say condition was 70-75% compared to a brand new pristine copy. Everything seemed to be fine until near the end when a message said something about "Illegal Mode". Just some extra information, I always create a WAV for the entire CD with it's Cue Sheet using EAC, and then create a clone (bin + cue) with ImgBurn. EAC said the disc had Sync Error and Read Error during around 20-30% of the rip session. I never finished the EAC ripping session because it took far too long with it's error correction (~38%, 25+ minutes into ripping). ImgBurn stated there were 0 Read Errors after competition, which took ~9.5 minutes. Results vary quite broadly. EAC says it detected Reading Error, but ImgBurn says there weren't any in the Read Error area, but the log says something about Illegal Mode and failed to read sectors near the end.

 

 

Here's the log:

I haven't spotted any questions being asked within your post, so I'm not sure how you'd like me to respond... if at all.

 

It's interesting that disc has an audio session followed by another containing both data and audio.

 

A traditional cd extra disc would have the data track in the 2nd session, but I've never seen one with another audio track following that. Weird!

 

EAC uses advanced methods to detect errors in the audio sectors the drive returns during the read operation. ImgBurn just asks it to read the sectors and writes it out to the file. It's down to the drive to detect and report any read issues. Data sectors have built in error correction stuff, audio ones don't - so a drive won't necessarily be able to report an issue when reading audio sectors.
