Decision helpError correction data can be either created in form of a separate error correction file or it can be placed directly onto the medium. Click on the answers to the following questions to find out which method is most appropriate for you.Do you need error correction data for a medium which already exists? More information on keeping error correction datadvdisaster helps protecting your media from data loss by forehanded*) creation of error correction data. Error correction data must be treated like normal backup data, e.g. you need to keep it available during the whole lifetime of the respective medium.The easiest way is storing the error correction data on the medium you want to protect. But this is only possible if the medium has not yet been written: To employ this method you need to create an ISO image first, then augment this image with error correction data, and finally write the augmented image to the medium. If the medium has already been written, or insufficient space is left for augmenting the image, you still can create error correction data in form of a free-standing error correction file. This file must then be stored somewhere else, e.g. you need to take additional provisions to archive your error correction files. More information about the pro and con of these methods can be found in the background information section. |
