There are no dedicated settings for reconstructing the image from the error
correction data.

<b>"Image" tab.</b> First choose the type of error correction data.
Pick the setting "ISO/UDF" (marked green) if you have an error correction file.
Otherwise choose "ECC/RS02" (marked blue) to process a medium which has been
augmented with error correction data.<p>
The adaptive reading strategy uses information from the error correction data to
make the reading process as efficient as possible. Activate it using the button
marked yellow.<p>

<b>"Reading attempts" tab.</b> The strength of the adaptive reading strategy lies in
finding the still readable sectors and avoiding the lengthy process of trying to read
defective sectors. Therefore select "raw" reading (marked green) as it will not cost additional
processing time, but reduce the number of reading attempts to the minimum values
(marked yellow). Use a moderate termination criterium of 128 unreadable sectors
(marked blue) for the first reading attempt. Do not activate raw sector caching yet.
If it turns out that these settings do not provide enough data for a successful
recovery they can be
<a href="howtos43.html">optimized</a> later.

<b>Not used tabs</b><p>
The "Error correction" tab has no influence on the reading process.
The "Misc" tab currently has only functions for creating
log files. This is helpful for sending in <a href="feedback.html">bug reports</a>
but should be left off during normal operation.
The "Appearance" tab allows you to adapt the output colors to your taste,
but these have no further effects on the reading process.
