Howdy Thomas,

Can I suggest you install zlib, HDF5, and netCDF-4, and try this
experiment with netCDF-4/HDF5 files?

Once you get netCDF-4 installed, change your create mode flag (in
nc_create) to include NC_NETCDF4, and build and run your program.

In netcdf-4 I call H5flush, which promises to flush buffers do disk.

Thanks,

Ed
