There were no red squares on the graph, a few yellow if I remember correctly...

Still not an excuse to read a 700Kb/sec


O but it IS, Dr. Watson

That explains everything!

No red squares is good news, it means that the damaged data on the CD can be ENTIRELY recovered thanks to EFM redundancy (error correction - remind U of anything ? ).

Still, the data corresponding to the yellow squares IS damaged, therefore it is normal for the reader's error correction to slow reading down to such a speed when encountering EFM anomalies: 700 Mb/sec is perfectly normal in such situations - notice that this is still much faster than when reading irrecoverable errors (ie. "red squares" in CDspeed).

Case closed!
