<h3>Examples of the error correction</h3>

|
<?php begin_screen_shot("Reading the defective medium.", "recover-linear.png"); ?>
|
|
<b>Recovery of aged media.</b> The medium processed here has become
|
|
discolored and partly unreadable in its outer region. A surface scan
|
|
yields about 23.000 unreadable sectors of 342.000 sectors total; resulting
|
|
in about 7,2% defective sectors.
|
|
<?php end_screen_shot(); ?>
|
|
|
|
<?php begin_screen_shot("Repairing the defective image.", "fix-image.png"); ?>
|
|
<b>Repairing the defective image.</b> The resulting image is still incomplete
|
|
since about 23.000 sectors could not be read. These sectors are now
|
|
reconstructed using
|
|
the error correction data created with dvdisaster.
|
|
During the recovery a maximum of 20 errors
|
|
per error correction block is encountered. This results in a peak
|
|
error correction load of 63%, meaning that this degree of damage is handled well
|
|
by error correction data created with default settings.
|
|
<?php end_screen_shot(); ?>
|
|
|
|
<b>Recovery needs error correction data:</b> The recovery process described above uses
|
|
error correction ("ecc") data.
|
|
Think of this data as a special
|
|
form of backup data (it needs less space than a normal backup, though).
|
|
Like an ordinary backup, the ecc data needs to be created
|
|
<i>before</i> the medium goes defective.<p>
|
|
|
|
So if you have a defective medium but never created ecc data for it - sorry,
|
|
your data is probably lost.<p>
