The settings shown here configure dvdisaster for reading the defective medium.
|
|
There are no dedicated settings for reconstructing the image from the error
|
|
correction data.
|
|
<pre> </pre>
|
|
|
|
<?php begin_screen_shot("\"Image\" tab.","fix-prefs-image.png"); ?>
|
|
<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>
|
|
Leave the remaining settings at the values shown in the screen shot.<p>
|
|
<?php end_screen_shot(); ?>
|
|
|
|
<?php begin_screen_shot("\"Drive\" tab.","fix-prefs-drive.png"); ?>
|
|
<b>"Drive" tab.</b> Leave this tab at the shown default settings for the moment.
|
|
Some drives might work better using the raw reading mode "21h". See the
|
|
<a href="howtos43.php#21h">advanced settings</a> for more information.<p>
|
|
<?php end_screen_shot(); ?>
|
|
|
|
<?php begin_screen_shot("\"Reading attempts\" tab.","fix-prefs-read-attempts.png"); ?>
|
|
<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.php">optimized</a> later.
|
|
<p>
|
|
<?php end_screen_shot(); ?>
|
|
|
|
<?php begin_screen_shot("\"Files\" tab.","create-prefs-file.png"); ?>
|
|
<b>"Files" tab.</b>
|
|
If your operating system can not create files larger than 2GB then you
|
|
must choose the "Split files " setting (marked green). In that case
|
|
dvdisaster will create up to 100 segments called "medium00.iso",
|
|
"medium01.iso" etc. instead of a single "medium.iso" file. Using this
|
|
option results in a small performance hit. This option is mostly
|
|
useful under Windows if the old FAT32 file system is still used. Leave
|
|
the other settings off as shown in the screen shot.
|
|
<?php end_screen_shot(); ?>

|
|
|
|
<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.php">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.
