According to http://www.gdal.org/frmt_hdf5.html, the syntax should be:

HDF5:file_name:subdataset

So it has little use to put the path before the HDF5:. I'm not sure if 
GDAL accepts the path before the file_name. Running the command in the 
same folder should be a safe thing. The output file might go to another 
folder.
