More on recovering images....

Here's a snipping from a window showing recovery of 28 image files from a camera card. The two at the bottom showing an Irfanview icon instead of a thumbnail were two files that had lost some reference data and couldn't be recovered, but 26 of 28 is still an excellent result, especially considering that these came from a card that was showing 'no images' and that some of these have been there for months.

If you start a search on a card, and it shows no results, you should start again, doing a "Surface Scan" which takes a few minutes, but finds otherwise hidden images. These above were found using that method on a card that was supposedly empty. This is because when something is 'deleted' it isn't always wiped out - the space is instead designated as 'available' for another use, to be overwritten by a fresh file. So if done soon enough, older images that haven't yet been overwritten can be recovered.
