I have been experiencing an error when attempting to use a Spatial analyst tool under Hydrology called the Fill tool,I am using this tool as part of a process to delineate a Water shed using a DEM model, however the errors received in the results are unknown to me, I carefully followed the steps, I have also used the data before for other analysis so I don't think it's corrupted in anyway. I've attached an image of what the error message entails also attached is an image of the file and the type.
