You should understand that a data CD-ROM has a third layer of error correcting code applied to it. This is because the error correction provided by Sony in the CD format was good enough for "perfect sound for ever" but completely inadequate by standards of computer data integrity, even back in the 1980's. From the computer standpoint, the Red Book CD is nothing but junk media. Anyone mastering audio CD's is well aware of the problems with this format, especially in the CD-R format which is like thermal paper printing and tends to decay with time, depending on temperature.

Without the extra error correction, your natural decimal points might have moved. Depending on whether they represented debits or credits, you might have considered the error beneficial.
