The writing quality measurements after the first burn were not good and CDSpeed produced an "UNRECOVERED ERROR" near the end of the reading procedure. We also saw POF errors. After the fifth burn, the PIE error count and level decreased a lot but CDSpeed showed that yet another disc had problems towards the end (outer region of the writing surface).
