Recovering Photos

Regardless of operating system or file structure a great last resort for recovering photos and other jpeg images is jpegextractor.

In my case, treating the whole disk as a single file and ignoring any file structure which had been destroyed, the command was:

java jpegextractor /dev/sdb1

to attempt a recovery of files from a harddisk on a usb connection.
