Thanks for the detailed explanation … now I know not to rely on usb for extremely long term storage … never understood how they worked until I read your comment.
It makes me wonder … what long term storage would be the best option for storing digital information … like to store something for 100 or 200 years? Anything beyond that and I would just rely on writing something in stone and burying it.
None … but if I had had a relative or friend tell me a story that someone had buried something there 50 years ago, I would have taken the time to dig it up while I was tearing down walls or breaking concrete.
