I don't know if you would want to trust this but I have found HIE has a
very sharp, almost sulfurous smell to it very different from most films.
For a fact at one time I could tell plus x from tri x in the darkroom by
smell alone. If you have a roll that you know is properly indentified try
comparing it againt the others.

Great suggestion... Another thing is the emulsion and the anti-halation
layer on the slide film.  The HIE's emulsion will give the film a green
color on both sides (pistachio green is the best way to describe it) and
the Slide film will be light tan on one side and dark brown to black on the
other. 

Cheers!

Try to find a camera with a window that let you see a little bit
of the canister (maybe you know someone that has this kind of
camera).  Just put (in total darkness) your unknow film in, open
the light and look through the window : you must be able to 
differentiate chrome and HIE.  As far as I know, this will not
harm HIE.  I don't recommand however to do this in direct
sunlight :-)
