This is just a reminder to back up your digital files regularly. This post was prompted a couple of weeks ago when I was contacted by a family I had photographed around 18 months ago. They had loaded their USB to a laptop and none of the photos would load or show up correctly, this meant they could not view or print from them :-(.
In this case, thank goodness, the laptop was to blame and the files were safe and showed and loaded correctly on another computer. Thankfully I'd kept their files as they were to be printed on some studio samples and displays, so in this case, I'd have been able to help if the worst had happened. But I can not keep files for everyone indefinitely and many images must be deleted to keep our systems working to an optimum.
However, imagine for a moment if it was the USB that had corrupted. I may not still have your files, as our files are turned over and storage is formatted and overwritten quite regularly due to the demand for my work.
Our USB's are the highest quality, but digital media can not be relied upon as archival storage.
So, here are some tips to minimise the chance of any problems
