I am having trouble importing into a file GDB in ArcCatalog (10.3) all of a sudden. With rasters I get a message 'No spatial reference found', even though the rasters 'do' contain spatial reference. And when I import tables, they import but are blank (fields only).
Any ideas what's happening here? Everything was working fine up until now.....
Are there any pathname or raster dataset name issues? That error message can come up when the raster cannot be written for some reason (often file naming).
