I was hoping that there was some advanced aging tests done on the media or there were people here who were having media that was failing (not when written, but years later) that was reported...
My cousin runs a testing lab on a variety of products. They use acid, heat, and air as well as other methods to advance age products to test reliability of things that are new and don't have established MTBF...like testing the control panel for a microwave oven to determine how many uses before it can be expected to fail.
And there are tests for printed media, like ink jet ink vs. pigment ink..
I could only wish..
