Which is why I have a few two year old jpegs on magnetic which won't open. Sure I have backups, but still...
50% of my ten year old jpegs on magnetic won't open; it was 10% of the same pictures five years ago.
Had you transfered your stock of jpgs to newer and cheaper media every 5-10 years, you would never have a problem opening up old digital content. The cost of digital archival is rediculously miniscle.
Coming back home to my film roots. Canon EOS-3 SLR, Canon EOS 1V SLR, 580ex flash, and 5D DSLR shooter. Prime lens only shooter.
