Hi Jamal,

The most common reason for this very generic error to happen is when ArcGIS finds something it didn't expect. I'm wondering if you may have been messing with the Value item in the raster table. It should never be set using table calculations. The way to get a field value from a raster table into the VALUE item is to use the Lookup function to make a new raster.

a thing I personally try to avoid is putting anything with a value outside 0-255 in a tiff, just for compatibility reasons with other software that reads tiff images that may or may not support something besides 8 bit integer values.

Is there a particular reason you want to push these values into a tiff raster?
