### dvdisaster as a complement to PI/PO scans

PI/PO scans are a valueable tool to assess and optimize the quality of burned media.

However, PI/PO scans are not a reliable means of predicting the durability of DVD media!

- PI/PO scans yield no information about how many more scratches or weeks of aging the medium can sustain before exhibiting the first unreadable sector.

- Copying media just because of bad PI/PO values often turns out as being too premature - sometimes such media remain readable much longer than expected.

- But without using additional tools like dvdisaster, one can not defer the medium backup until the first read errors occur - that would definitely lead to data loss.
