So...just got home from a photo shoot with three seniors (all are friends) and I'm gettting really nervous because my stupid microdrive card seemed to mess up right in the middle of our shoot, and I just switched to a CF card. Now it looks like the Microdrive is messing up my 20D and my card reader isn't reading it. Basically, if I try to put it in the 20D it can't show any pictures that I took on it and then the a little red light lights up and it doesn't go away even if I turn off the camera. Have I lost those pictures? Is there anything I can do to get them back? Help please!
