8.1.10 Testing of Existing Recorded Discs

8.1.10.1  If data on recordable CD or DVD was not tested at the time of creation, it is critical that tests are made of their current state. Discs must be subjected to rigorous error testing as their current error rates play a major part in determining their further life expectancy. If error rates are measured above the levels expressed in table 1, contents should be immediately transferred to new media.
