Unless the image on disk was corrupted, in which case you'd have no idea.

This is exactly what I've seen many, many times. Both in computer systems and especially in embedded systems. The last time I had this problem was a couple weeks ago at the company I was working for. It took days to determine what version of code was in the failed units because we did not have a string as Carl describes embedded in the image.
