Recovery of information deleted from the Olympus camera

Photos were deleted from the removed disc inserted into slot of Olympus FE-230 camera. At first I got only a flash-card. My card-reader did not define it at all. Then my client brought it together with the camera, so the card was correctly defined.

But, alas, the problem could not be solved as pictures were deleted from the camera in a secure way. All the surface, considered to be free, from the point of view of FS, was filled with FFh pattern. Data recovery in this case is absolutely impossible. Be attentive when you press a "delete" button on your camera!
