My neighbour accidently deleted all photos on the camera without having them transfered to the harddisk. The SD card was never used before and the card was not formatted after deleting all photos. This should be recoverable.
From lifehacker.com I was directed to PhotoRec to recover lost photos. PhotoRec scans the disk and looks for files based on the unique blocks filetypes start with and recovers every file it can read.
The process took about 15 minutes and recovered 250 Mb of photos from a 4Gb SDHC card. Making the neighbour jump for joy and providing me a new blog topic.
