A CD audio file has about 800 error correcton bits for each 3200 bits of actual data. These are for correcting errors due to poor pressing of the CD, scratches, misreads, etc. When the mac copies an audio file from a CD using to the hard disk the finder it converts it to an AIFF file. Does it use the error bits to clean up the data, or just store everything, or ignore the error correction data completely. ??? Thanks Oliver Reid

This has to do with the Red Book standard, have a look to http://www.disctronics.co.uk/technology/cd...cs/cd_books.htm for more infos. Bye.
