The dvdisaster project:
dvdisaster provides a margin of safety against data loss on
CD and DVD media caused
by aging or scratches.
- dvdisaster creates error correction data to compensate
read errors which are not correctable in the CD/DVD drive.
- dvdisaster tries to read as much data as possible from defective media.
Afterwards unreadable sectors are recovered using the previously created
error correction data. The maximum error correction capacity is user-selectable.
- dvdisaster operates at the image level
and does not depend on the file system.
If you create the error correction data in time and keep it at a safe place,
you have a good chance of recovering the medium contents from typical read errors
and to transfer your complete data onto a new medium.
Examples of the error correction...
