Pyramid displaying 'No Data' Value

[chadhickman]

I have reclassified some raster data and changed the 'No Data' value to zero. After reclassification I deleted the 'No Data' (which was 0) and it gone, however, Arc keeps asking to build Pyramids so I went a head and built them but once it finishes the 'No Data' value reappears but I am unable to find it and delete it from the attribute table.

Does anyone know a way to delete the 'No Data' value from the raster after the Pyramids have been built?

Thanks!

Note: I conducted to a similar study with Arc 10 and I did not have this problem, I am running 10.1 now.

For your raster, what is the value set for the NoData in the source properties?  Also is your raster an irregular shape?  If so, then there will be extra pixels added to the created raster to make it square.  Also as a courtesy, the program will usually add one pixel around the outside to avoid losing data.  The default behavior in ArcMap is to provide ways to handle the display of NoData, not necessarily eliminate it entirely.
