I can feel your pain. Three years ago I burnt my entire first years worth of Bryce projects to CD, br4 files, raw TIFF renders, the whole shebang. I them promptly deleted the files from my computer (to save precious space) knowing that my files were safely archived. Or so I thought. Several months later I attempted to retrieve some images from the archive, only to find out the only thing I'd burnt to the CD was a Windows "shortcut" to the folder where the images used to be (which was long deleted). ARGH!
