<h3>The dvdisaster project:</h3>
|
|
|
|
CD, DVD and BD media keep their data only for a finite time (typically for many years).
|
|
After that time, data loss develops slowly with read errors
|
|
growing from the outer media region towards the inside.<p>
|
|
|
|
<b>Archival with data loss protection</b><p>
|
|
|
|
dvdisaster stores data on CD/DVD/BD (<a href="qa10.html#media">supported media</a>)
|
|
in a way that it is fully recoverable even after some read errors have developed.
|
|
This enables you to rescue the complete data to a new medium.<p>
|
|
|
|
Data loss is prevented by
|
|
using error correcting codes.
|
|
Error correction data is either added to the medium or kept in separate
|
|
error correction files. dvdisaster works at
|
|
the image level so that the recovery
|
|
does not depend on the file system of the medium.
|
|
The maximum error correction capacity is user-selectable.<p>
|
|
|
|
<b>Common misunderstandings about dvdisaster:</b>
|
|
|
|
<ul>
|
|
<li>dvdisaster can not make defective media readable again.
|
|
Contents of a defective medium can <i>not</i> be recovered without the
|
|
error correction data.<p></li>
|
|
<li><img src="images/exclude_from_search_terms.png" align="middle"><br>
|
|
Such functions are outside the scope of dvdisaster's internal design and goals.</li>
|
|
</ul>
