<h3 class="top">Testing image compatibility</h3>
|
|
|
|
<b>Why dvdisaster uses ISO images.</b>
|
|
Some dvdisaster functions work on image files stored on hard disk.
|
|
CD/DVD/BD drives are too slow for carrying out the required access
|
|
patterns, and they would wear out quickly. However hard disks are designed
|
|
for this type of access, and they do them quickly and without wear.<p>
|
|
|
|
<b>Testing image compatibility is important.</b>
|
|
During the work with dvdisaster you can (and sometimes must) use ISO images
|
|
which have been created by third-party software. Unfortunately ISO images
|
|
are only informally standardized. Typically all programs will produce
|
|
the same images when advised to use the ".iso" file format, but it is
|
|
better to make sure that a usable ISO image has been created:
|
|
Processing a non-iso image with dvdisaster will result in
|
|
unusable error correction data. Especially, formats like
|
|
<b>.nrg are not suitable</b> for processing with dvdisaster.
|
|
<p>
|
|
|
|
<b>Possible scenarios.</b> The following situations require exchanging
|
|
ISO images between dvdisaster and a third party software:<p>
|
|
|
|
<b>a) Creating error correction files from ISO images made by a CD authoring software</b><p>
|
|
|
|
A CD/DVD/BD authoring software is used to create an ISO image.
|
|
This image is used for writing the medium and for creating the
|
|
error correction file. When using the authoring software for the first time
|
|
with dvdisaster, make sure that
|
|
the <a href="howtos91.php">image was written to the medium without
|
|
modifications</a>.<p>
|
|
|
|
|
|
<b>b) Augmenting ISO images with error correction data</b><p>
|
|
|
|
dvdisaster adds "invisible" error correction data to the medium in order to
|
|
minimize interference with other applications.
|
|
Therefore it is possible that some CD/DVD/BD writing software will not properly
|
|
write the error correction data to the medium. Make sure that your writing
|
|
software does <a href="howtos92.php">correctly transfer the error correction data</a> when using it with augmented images for the first time.
