Background information

### 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 data must be created before the medium fails, preferably at the same time the medium is written.

- Error correction data requires additional storage space either on the protected medium or by using additional 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.
