Don't just think that your DVDs are safe enough to hold all of you important pictures without some sort of recovery data. A small scratch can quickly cause errors on the disc. A great way to create recovery information for a DVD/Blu-Ray is using "DVDisaster". I have tested it using a badly damaged disc and was able to recover all of my data from it. I been using it for the past year and found it to be a great way to make sure your archived data is recoverable. You can create recovery info to be put on a disc or a separate file on your hard drive.
