Thanks For the ... Eight-Track, Uncle Alex
Uncle Alex writes "My niece just turned one year old and her parents have asked that, instead of the usual gifts, we each contribute something to a time capsule to be opened on her 17th birthday. Multiple members of my family want to contribute digital data — text, video, music files. They came to me (the closest thing to a geek our family has) wondering: what's the best way to save the data to ensure she'll actually be able to see it in 16 years? Software might be out of date, hardware may no longer be used... any suggestions?"
Recently it was mentioned on a documentary I've seen: 10,000 years of evolution, and the best thing to conserve information we came up with was stone tablets.
It's unfortunately true. The more sophisticated our means of storage are, the more brittle and frail they are. Essentially, you would have to bury not only the medium but also the means to play them back. The tricky part is finding out "where to stop".
"Thanks for the 8track" was a quite good tagline for this problem. 20 years ago, an 8track would have been the thing to store information on. Today, you would have a hard time finding a player. And the problem gets worse with every year. Magnetic tapes, VHS or Beta, dominated the video market for over two decades. DVD didn't dominate for one. BluRay is probably going to be replaced before long. The time between generations of players is shrinking quickly. Soon we'll see, if you're not an early adopter, you're already lagging a generation behind.
The most sensible way, and a worthy geek project too, would be to create a playback device made entirly from standard off the shelf parts that you may sensibly assume to be still available in a few decades, put the packing list along with the content you want to preserve into the box and make sure you also store your content in a way that survives the test of time.
You only have to bridge about two decades. It would be a very interesting project to try something like that with the goal to make information last millenia.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
Most flash drive manufacturers state that their drives are not good for archival storage. They expect to lose data before 10 years have passed.
This is absolutely correct, no flash memory. Unlike hard drives (and tapes, for completeness), which store data as magnetic regions, flash memory stores actual electric charge. While the magnetic domains on an HDD are permanent (unless overwritten or degaussed), the small charge in each flash media bit will slowly leak away. The drive should still be usable, it just won't have your data on it anymore.
A portable hard drive might be the best solution, for its small size and relative permanence of data. Perhaps even an iPod, preloaded with music that it can play, pictures and video it can watch, and files that (assuming USB and the files system are still around) will also be available. One iPod with everyone's files could be a good split, and a great trip down memory lane. Just be sure to pack in a USB wall charging socket, just in case.

+1. My father in law knew he was dying for several years, so he spent a part of that time on a round-the-world trip, revisiting all the places that were important to him. Then he compiled several albums, with original pictures from his youth, newer pictures from his trip, and stories about what those places meant to him. It's an incredibly powerful document, and it's the best thing he could have left for his grandkids, all the more so because in this age of high mobility and disposable housing we no longer have family histories.
