As a HDF5 user, I would not expect HDF5 files with the same data to match with a tool like diff (or the diff tool of git or any other vcs). HDF5 uses more advanced techniques with respect to plain ASCII files, which is why we use it. As a consequence you should not expect any kind of binary equality between files, even between files created similarly.
it may not be common for HDF5 users to request or expect "bit for bit" equivalence. It *was* a pretty important way to verify correctness in climate codes using NetCDF (I suppose bit-for-bit equivalence is now impossible with HDF5-backed netcdf files?).
