Questions and Answers
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.
