Advantages of using dvdisaster:
- Protects against aging and accidental medium damage (within certain limits).
- Read error tests run faster than quality scans;
up to full reading speed depending on the drive.
- Cost-effective: Media must be replaced with a new copy
only when they are really defective.
Limitations of using dvdisaster:
You need a backup strategy and at least 15% of additional storage.
- 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.
