Hello All,
I am trying to recover .jpgs that were on a SATA drive that was formatted by
mistake. No backup of course. Foremost has done a wonderful job of recovering
several tens of thousands of files. Unfortunately many of them are either
irrelevant (cached web fragments, etc.) or damaged. The most common type of
damage is shown when trying to view them in Nautilus, when I get a message
saying, "unsupported marker type."
It seems about 30% - 40% of the files recovered are damaged in this way.
Assuming that all the data is really there but you have extra on the end, then
you might be able to use convert to read the input and only output picture data.
identify might be able to help you sort images from not images, and corruption.
They aren't my images and I am not able to gauge what is worthwhile or not but
I would like to do some triage by only considering those of a certain minimum
size (easy to do) and not damaged (no idea.)
So does anyone know of a program I can use to only copy files that are not
damaged? I can sort out the teenies, but don't see how to proceed after that.
man ImageMagick
man identify
man convert
