Some great information regarding storage of your digital photos.

Guidelines for image storage
Today when the master copies of our images are usually digital (even slide workers often put a lot of work into digitising their transparencies) it’s easier to store and organise thousands of files than it was to do the same with physical prints/negatives/transparencies. But it’s also easier to lose everything when you make a mistake (or a disk crashes, or any other disaster happens).
