Ed,Here is some documentation on Fletcher32 http://www.hdfgroup.uiuc.edu/RFC/HDF5/ARCHIVE/H5checksum/
This document describes the final design and implementation http://www.hdfgroup.uiuc.edu/RFC/HDF5/ARCHIVE/H5checksum/EDC_spec.htmChecksum is ON by default, i.e read operation will fail, but there is an API that allows you to disable checksum and get data back.

Howdy Guys! With the release of HDF5 1.8.0 I am taking a spin through the netCDF-4 documentation... I realize that there is very little said about the fletcher32 filter. Because I really don't know anything about it. I know you can turn it on with netCDF-4! But I don't know why you would want to. In the HDF5 docs I find very little, only that this is the "Fletcher32 checksum filter." What happens if the checksum doesn't add up when reading the data? Thanks!
