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.
