Some high-density tapes will fail if you drop them on the floor. I
think we can all agree that any media type has the potential to fail,
which is why we use multiple copies on different physical media, so if
one fails you still have another one. If you are storing all of your
backups on a single tape/disk/cd/dvd/bd/holocube, you are doing it
wrong.
