HDFView cannot handle big files or files with a lot of objects. This is a known limitation that we are trying to address in the next major release. You will need to use other tools to confirm that the file is indeed corrupted. > > I have to assume the file is corrupt.

Could you please try to run h5check tool to see if HDF5 metadata in this file is corrupted? If h5check doesn't find anything, try to run h5ls to see how far you can traverse the file.
