Expert selects 8GB blacks SD card not being detected

My Expertselects 8GB Blacks SD card isn't being detected on any device (laptop, camera, etc.) not even in the device manager on my PC. It was working perfectly one day then the next it wasn't.

Does anyone know a way that I might be able to fix it or at least recover the pictures off it?
