Why should I use Test & Copy? How to read the CRC codes?

If you don’t like to use the secure modes, and the burst mode does not have error correction, the best possibility to check if an error occured is to copy and test the track. For each read and each track, the appropriate CRC column is filled with the actual CRC code. One CRC code is unique for a set of data. So by comparing the CRC values you could be quite sure that both reads resulted in the same file.
