<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.

<?php begin_howto_shot("Reading process successful.","adaptive-success.png", ""); ?>
|
||||
<b>The next actions depend on the outcome of the reading process.</b>
|
||||
The reading process terminates automatically when enough data for a successful recovery
|
||||
has been gathered (compare the output marked in green). In that case continue the recovery
|
||||
by clicking on the "Fix" button as described below.
|
||||
<?php end_howto_shot(); ?>
|
||||
|
||||
<?php begin_howto_shot("Reading process failed.","adaptive-failure.png", ""); ?>
|
||||
The reading process will also abort if it could not find enough readable sectors
|
||||
(see the output marked in red). The image is <b>not</b> yet recoverable in this incomplete state.
|
||||
Please try to gather additional data following the tips shown in
|
||||
<a href="howtos43.php">advanced settings</a>.

<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.
