editing rasters

Working in 10.0, we have an ArcGIS layer of sample land cover.
Some of the pixels need correction but the layer is not available for editing.
We have created a mosaic dataset in a personal GDB and added the raster to the dataset; but in edit mode the layer is not selectable and the ArcScan and Raster Pointing tool bars remain gray.
What is the procedure to modify the pixels?
