sometimes data does get lost - BACKUP YOUR DATA

There are an unlimited number of reasons why photos (and data) go missing.
User, software or hardware error can be the causes.

The only surefire method of recovering all your vital photos and data is to
have a backup copy stored on a SEPARATE storage medium
from the disk where the originals are stored. Personally, I make two copies
to CD-R or DVD.

We won't hear folks ask: 'I deleted all my .. (accidentally).., can I get
them back?'
