Raster data not visible after mosaic

I have a big raster dataset with elevation data (40GB) and want to add a view km2 of elevation data (4GB) to the original dataset. I did this several times with the Mosaic-tool, a time consuming job. Every time the Mosaic-tool succeeded, but the result is strange. I get a dataset where parts seem to be missing around the newly added parts. However, when I zoom in, the missing parts are showing up. It's also possible to get info from the missing fields. So the data is available, but not showing up when zoomed out..

What is going wrong? Is there a way to repair the dataset?

The datasets are all ESRI Grids, Generic 32bit floating point, 1  band.

Thanks in advance!

Have you considered using a mosaic dataset?  A mosaic dataset will allow to quickly catalog your imagery and view it as a seamless mosaic.  This will cut your processing time from hours to seconds/minutes.

my guess. you should try to build overview, pyramids and statistics once again and hope this helps.
