How To Verify CD-R Data Retention Over Time?
Peter (Professor) Fo writes "I’ve recently had two CD-Rs reported to me as faulty which are just 3 years old. This is worrying — I suspect the failure rate for this batch could be 10%. When researching CD longevity there is old and unreliable information; pious ‘how to cosset your discs so they last 100 years’ blurb; and endless discussions of what sort of dye to use, don’t use cheap media, burn slower (or don’t), but not much by way of hard facts besides there’s a lot of data loss going on. Does anyone know of a generic utility (win or *nix would suit me) that can map sector readability/error rates of CDs?
