About 98% of the CD-Rs I burned 7 years ago are find, I know the
ones there were going bad and have saved everything that was on
those few.

I friend of mine who works for a telecomunications company has told
me that they have noticed an interesting trend: data storage on CD's
seem to "fade" from some discs and not from others. He says their IT
is unsure if it is due to the discs themselves, the burners, or
something else. Their theory is that the pits burned by the laser
might not be deep enough in the plastic, and with time the plastic
fills into the void erasing the signal.
Just relaying the information: "Don't shoot the messenger."

It's a dye thing...not a plastic thing...

Well, as newer and better dyes are created, we can go to the store
and buy the new blanks, and then bring them home and duplicate our
older disks onto them, and for a couple of dollars a disk, we can
extend our archival lifetimes into the distant future......

I generally agree with that.
-But there a part of the issue that I think remains a significant
problem...that being those long-forgotten family "finds..."

-Like the huge box of slides I found a few years ago, shot by my long-gone
grandfather.
Nobody even knew he had these boxes, and the boxes hadn't been been touched
in over 50 years.

-Had these been on disks, it is almost certain that they would be
unreadable...either because the format was long since replaced (meaning no
way to read them), or the data was bad.

It is these sort of scenarios where I DO think digital will be a problem.
Most families don't have acting, digital, "museum custodians" who always
maintain everyone's files.
Nobody had to "mainain" those boxes of slides... They just had to be
discovered by me.

Don't get me wrong... I think there are advantages to digital in terms of
the *ability* to keep perfect originals in more than one place, etc., but
there are scenarios where digital could have a shortened life--perhaps
simply due to death, or secrecy of existence...or ignorance regarding proper
maintenance at any point/generation in the future.
