It is true that undamaged CDs deliver all of the data in huge majorities of the time. The error correction logic is quite good. The RedBook specs also include specs for what to do when the errors can not be corrected. It happens, somewhere between rarely and extremely rarely. When it happens, the player fakes it. For non-critical listening, you are unlikely to notice it. EAC and other PC programs use a different approach to reading, but the result is essentially the same. And they are highly sucessful. I don't know what EAC does when it just can't extract a block from the CD. I've never had it happen. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
