Advantages of using dvdisaster:
- Protects against unintentional medium damage (within certain limits).
- Read error tests run faster than PI/PO scans;
up to 16x speed depending on the DVD drive.
- Cost-effective: Media must be replaced with a new copy
only when they are really defective.
Limitations of using dvdisaster:
- Error correction file must be created before the medium fails.
- Error correction files require additional storage space and
must be stored on reliable media.
Using the standard settings the additional
storage space amounts to 15% of the original data size
(approx. 700MB for a full 4.7GB DVD).
- no guaranteed protection against data loss.
