### Screen shot: Recovering the medium image

The screen shot shows a recovery using an error correction file; for augmented images the output will differ in the head line. The repairing progress will be shown in percent.

- The message "Good! All sectors are repaired." confirms that the medium image has been fully recovered. The repaired image can be written to a new medium using a suitable CD/DVD recording software.

- If uncorrectable sectors remain after this stage, try reading the image again (some hints for re-reading). dvdisaster will try to re-read only the missing sectors, and this might retrieve enough missing sectors for a successful error correction run.

- The red error graph does not correlate with the spatial arrangement of read errors on the disc: The error correction method is explicitly built to achieve an equal distribution of medium read errors over all error correction blocks.

  The green line marks the maximum capacity of the error correction. If this line is exceeded, the image can not be recovered with the currently available data. In case of tight misses another reading attempt might help.

- When the image has been read in by the adaptive reading strategy, the error correction load will always be maxed out.
