There's an episode of TNG called The Most Toys where this asshole kidnaps and fakes Data's death so that he could add the android to his personal collection of stuff. Geordi is the only one who refuses to accept that Data died in a shuttle accident and eventually proves that he didn't. Meanwhile, in the movie Generations, Data is wrought with guilt and shame after Geordi is kidnapped by the baddies. He blames himself and while the emotion chip he had installed earlier in the movie was obviously hyping up his emotions, they were still there.
