[Recuva working with usb drives/SD cards/cameras/cell phones?]

It works on my digital camera.

[Secure deleting files]

Every USB device I plug in my computer: Ipod, Digital camera, Printer. Windows says that it does not recognize the device.

 

I've secured deleted a whole lot of files that I found with Recuva on my C: and since then, I have this problem.

 

Can anyone help me solve this problem?
