I'll give you two from direct personal experience - they may not be what you thought you were asking for, but they make the same point. 1) All files I saved in .STN format. Did you say "What the dickens is that?" -it's the format used by Genuine Fractals, which I am sure you remember, now subsumed into OnOne Perfect Resize, currently at v9. To quote OnOne "The only way to open STiNG files is via Adobe Photoshop if Perfect Resize 7.5 or earlier is installed". Doesn't matter if the bits are corrupted or not, the format has been abandoned. 2) All files I backed up to a so-called online backup system nearly 20 years ago. They went through two acquisitions, and the new proprietors felt there was better business to be done elsewhere. Service was simply terminated, as if they had gone out of business (they may yet do so, of course). Doesn't matter if the bits are corrupted or not, again. And a third of which I have no personal experience, simply technical press articles this week. Look out if you use SSDs for backup, as 1s magically can become 0s, as Spencer rightly says. You have to keep 'em cool.

Re: So much for "film is forever".. Importance: Low I think the fact that while most of us have switched to digital our body of work is now (roughly since the year 2000) is in danger is very on topic as I think its big news where can I sell my digital bodies and re buy back my film ones?!? I'd like to hear a roll count on the LUG of people whose old digital files have given up on them or have gotten all wonky. Other side known as digital fading. I'm being told by you that my digital files are deteriorating I JUST CAN SEE IT.!! I don't think when you back up digitally to do it redundantly is the end of the world. I used to back up my whole hard disk with floppies. A stack of them many inches thick. And I had several sets of them in case one of them was bad and for other reasons. It was an automatic process but doable. Now its just copying one hard disk to another sometimes a slightly bigger one. Can be done in ones sleep.
