Recovering of Datas

[photon]

Accedentally I have deleted ny datas from my SD Digital cam card and from my USB pen drive. How the datas can be recovered?
I have tried PC file recovery and easy file recovery. But the format of the pem drive is unidentified by the software.

I havfe heard something like image resque. Form where i can get that ?
