When you stick an audio CD into Windows and Explorer shows you a bunch of CDA files, it's simply giving you a view of what's on the CD that better fits the Explorer interface model. Those files don't actually exist. A red book CD (audio format) has two levels of error correction codes. A yellow book (data format) CD has three levels. When you put an audio CD into a data drive, it doesn't suddenly acquire an extra level of error correction capability: the redundant data simply doesn't exist, and information cannot be invented out of thin air. Red book CDs cannot be read as yellow book ones. > In other words, what exactly happens when you open a audio track as a > data file that has errors in Explorer and try to copy it?

If there are uncorrectable errors on the audio CD, then whether they are concealed when you access it through Explorer will depend on the firmware of the CDROM drive: some drives implement concealment, and some don't. As it happens, I'd never tried copying a track from an audio CD using Explorer, so I've just done it: dragged "Track01.cda" from the CD drive to the hard disk. What I ended up with was a 44 byte file containing a RIFF header and no audio data at all. This was using Windows 2000. Can anyone tell us what happens under XP? -- cliveb ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=18991 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
