<b>"Image" tab.</b> Selecting the proper method for determining the image size is important.
The setting "ISO/UDF" (marked green) usually works in any situation.
Pick the selection "ECC/RS02" (marked red) only if you are sure that the medium contains
RS02 error correction data. Using the error correction (ecc) data
will improve scanning results,
but searching for non existing ecc data will cost several minutes. <p>

<b>"Read attempts" tab.</b> Adjust the reading attempts settings as shown here.
Using larger values causes unnecessary reading activity but will not improve
the scan.
The option "Read and analyse raw sectors" (first green marking) uses C2 analysis and possibly
more raw data reported by the drive for a better assessment of CD media quality. This setting does
nothing for DVD and BD media, but it is safe to remain activated unless it causes problems
with your drive reading CDs.
After a read error no less than 16 sectors should be skipped (second green marking);
when scanning badly damaged media this setting can be
<a href="howtos14.html">optimized using larger values</a>.<br>
Performing multiple read attempts is not recommended during a scan; set the number of retries
to 1 in the three places marked in orange. Collecting raw sectors should also be off
during the scan.<p>
