Hi just read in TNP yesterday about a program that might help. It was featured in their tech section which was reviewing the new Sandisk CF cards and card readers and can be found in this link

Quoted from the article,
"Also bundled with either card or reader is RescuePRO software, which can resurrect images you accidentally deleted from any memory card.
During my testing, I even managed to recover photos that had been formatted twice over!"
Hope it helps!
