What version of gdal are you using?  Starting with 1.10, it
gdal_translate should do what you want.  Specifying -eco or -epo makes
it an error:

-epo: (Error when Partially Outside)(GDAL >= 1.10) If this option is
set, -srcwin or -projwin values that falls partially outside the
source raster extent will be considered as an error. The default
behaviour starting with GDAL 1.10 is to accept such requests, when
they were considered as an error before.

-eco: (Error when Completely Outside)(GDAL >= 1.10) Same as -epo,
except that the criterion for erroring out is when the request falls
completely outside the source raster extent.
