hdf5save is a function in the hdf5 contributed package, so you should 
start with its maintainer, Marcus G. Daniels <mdaniels at lanl.gov>.  But 
before you bother him, make sure you're using the latest release of it. 
  If you still have problems, give him the usual details requested in
the posting guide.
