How do I select drives?

I am probably missing something obvious. I have just installed Recuva. It is not clear how I select drives, or whether Recuva does it automatically if it detects that there is media there. Only the C drive (my hard disk) is presented as an option. just to test it I stuck a CD in my "I" drive, and the drive was not identified by Recuva. My need is to check for accidentally deleted photos on my camera, I normally connect the camera via a USB hub (K drive).

Grateful for help

There is a help guide here :)
