***Guys, just to wade in on the longevity of digital storage, I think some of you have drastically missed the point.***
So how do you inform Joe Public, also I wonder what the losses are so far for digital media because of hard drive crashes, dodgy CD's, memory cards failing and so on, and what about all those prints from ink jets on cheap paper with no backup of JPG's.
I don't want to hijack the OP's thread too much. I don't purport to know how to convince people to think about their actions and realise the stupidity of not backing up, nor to convince people not to print pics on A4 paper then delete the original file. If I had that wisdom, I'd be out stopping wars and suchlike
I only purport to have the expertise to confirm that with a little drag-and-drop, digital will last forever. Guaranteed.
