[Leica] So much for "film is forever"..

[Spencer Cheng]

We are going way off topic here so this is my last comment. I did not say to store your digital media using microfiche. 

I am aware of a group of digital archivist (including someone from NIST) working on how to preserve digital media in a standardized fashion.

Best practice digital media preservation currently require regular active copying and indefinite transcription of digital media to protect again deterioration of storage media and format obsolescence. 

If you are not doing both, your stored media is likely to stay ephemeral despite of what you believe. 

Mark, do as you wish but 1’s magically becomes 0’s in digital media whether you believe it’s going to happen or not. Good Luck.

Regards,
Spencer
