I am interested in exploring the kind and severeness of the damage. How old is the reader drive ?

This feels like it would be a lot of work. To my experience, degradation of once verified media is rare, even long after they have been written. More probable is drive degradation. (With re-usable media stored for a long time, there is an increased probability that they fail to take new data. But that's a different problem.) Have a nice day :) Thomas
