raster extent too large

Hello all,

I know this is something simple, and I've tried looking for it but couldn't find anything exactly like this:

I "clipped" a raster data by using the Raster Calculator with the Environment Settings-Raster Analysis-Mask set to a much small box in a polygon shapefile. When I load the raster into the data frame, I get the data I want, but the extent is the same as the original raster. Why is it doing this? This is fine for display, but I can't do anything to further processing with it because all other outputs end up with the same extents.

I tried using the Extract by Rectangle as well (on the newer file), but the extent remains the same.

I am running ArcMap - ArcView with Spatial Analyst on Windows 7.

Thanks for any help

Ah! Found the answer! Though I did all the things describe below before, I didn't do it exactly this way. But for those who might be wondering (as I was) do this exactly and it will work:
