Yesterday, even using the Raster to geodatabase tool did not work. This morning before opening ArcMap, both 'Copy Raster' and 'Raster to Geodatabase' worked flawlessly on my remaining data in ArcCatalog. However, after I clipped a raster in ArcMap, which I couldn't save in the geodatabase everything stopped working again on any data I have tried to import into the geodatabase.
I also tried to edit a polygon feature class which is in the same database, it would not let me delete a feature which I had altered before. There was no error message and when I tried to create a new empty feature class in the database and bring it into ArcMap I was given a 'The table was not found' error.
I'm starting to think this is some sort of error with the database itself? Maybe the database has been corrupted in some way? I've never had any of these problems before in ArcMap 10.1 or previous versions I have used.
