<b>Watch the reading process progress.</b>
The adaptive reading strategy performs a systematic search for readable
sectors. You will observe temporary gaps which will be closed in later
stages. Usually this effect is less pronounced as shown in the screen shot. If all defective
sectors are located at the end of the medium the reading process may even stop before touching
the first defective sector.

<b>Watch the progress of the recovery.</b> The adaptive reading will stop as soon
as enough data has been collected for a successful recovery; therefore the error correction will
always be loaded to the max. This causes the display of the massive red area in the "Errors/Ecc block"
graph and is no cause for worry. Depending on the medium size and your system speed the recovery may take
several minutes to hours.
