recovering netcdf files?

[Karishma <karishma@xxxxxxxxxxxxxxxxxxx>]

Dear All,
I have some netcdf files which have data in them and were  apparently not
properly closed. When I examine them using ncdump they report zero data
points, although the size is a few meg. 
Is there a way of recovering them ? I have looked up the netcdf web page
but couldn't find anything obvious.
Thanks,
Karishma
