dvdisaster provides a margin of safety against data loss on CD and DVD media caused by aging or scratches.

• dvdisaster creates error correction codes 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 code. The maximum error correction capacity is user-selectable.

If you create the error correction code file 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.

Changes in dvdisaster 0.72.1 :

- Pablo Almeida provided a Portuguese translation for the screen text. - Added workaround to avoid Win XP freezing on certain CD-RW/drive pairs.
• dvdisaster 0.72
- Igor Gorbounov completed the Russian translation
- Documentation and locale cleanup for en, de
- Graphical bug: red/green sector markings were incorrect when doing linear reading with high sector skip numbers. Fixed. Speed curve will no longer travel below the x axis.
- fixed rare crash while linear reading due to a race condition by improper ClearCrcCache() usage.
- fixed bogus dead sector warning in the linear reader after encountering unreadable sectors
- made adaptive reading pursue raw reading more aggressively; effectively trading in place re-reads for seeks over the medium.
- --help output for --defective-dump was complete nonsense. Fixed.
- detection of read errors at the end of track at once disks would sometimes cut off too many sectors when doing multiple reading passes and a carefully crafted number of extra read errors occurred. Fixed.
- fixed crash in command line mode when doing multiple reading passes.
