Some information, that is important for persons, is believed to be always in safe. Such attitude usually intensifies a risk of its loss. Users must always think about safety measures and the greatest way is to protect both physical and logical systems from any defects.
Physical damage can happen any time to any of the info carrier. A CD or DVD disk may be scratched and some of its metallic substrate will get lost. Hard disk may stop working too, when its head will be broken or its motor stop.

And infinitely recursive directories appear. Usually computer systems have their own recovery programs, but they don't perform their function in a good way.
