Sorry to have inspired rancor when I was actually trying to
make the point that backups, which many people still do not
create, have real value. Unfortunately, this only becomes
clear when they are needed. ;-(
It seems worth pointing out that a backup does not exist until
it has been successfully read back. This often omitted step
should be done immediately after completing the backup, and
should preferably be done by *comparing* the backed-up files with
the originals. It is unfortunate that many "backup" programs,
in the interest of speed, either do not provide or make it easy
to bypass this critical step.
This is not a trivial point, since many major companies with well-
established periodic backup policies have had failures, only to
find that their backup media is not readable. It can happen to
anyone.
BTW, when people experience serious disasters, one of the things
they most often regret losing the most are their family photos.
Digital technology for the first time makes it easy to have
multiple copies of all important files, with at least one copy
stored "off site" for protection against physical disaster.
It's worthwhile to periodically put a few DVDs in your safe deposit
box, and/or exchange them with a friend or relative some distance
away. This personal "disaster recovery plan" can virtually
eliminate the possibility of losing precious files.
It may be that your CD and DVD were written with "packet writing"
drivers (common for "drag and drop" copies), and are not complete
"sessions" that many readers will expect. There are recovery programs
for optical media, too, that can read data from such discs.
I hope you are successful in recovering your pictures.

I expect that the OP's level of pain is pretty high
regardless of my response.
I think that one purpose of a public forum is to teach
others how to avoid problems. It is far to easy to assume
that "It won't happen to me."
