Since most images are compressed, checking the band/tile offsets & sizes (and then reading each band/tile) is a good way of checking for this (corrupt file).

The above statement "most images are compressed" reveals your area of focus. In the RGB/color world, a large portion of the images are not compressed, leading many people to believe that TIFF is an inefficient format which does not support compression at all. In the black/white monochrome world, most images are compressed.
