Hi Saji, Versions 6.6 and higher of Ferret can read hdf files with no need for you to do anything. What version of Ferret are you running? Error -51 is coming from the netCDF library, and the library gives the translation of that error code as "Unknown file format". It indicates that either the netCDF/OPeNDAP library in your Ferret version can't read hdf files, or that the file itself is not recognized by the netCDF library.
