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.htm
Checksum 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!
Ed
