I am not sure about your syntax at ://Data. This worked for me:

gdal_translate -a_srs EPSG:4326 -a_ullr -180 -90 180 90 -of "Gtiff" 
HDF4_SDS:UNKOWN:"LISOTD_HRFC_V2.3.2013.hdf":0 test.tif

with all files in the same directory. You have to run gdalinfo first to 
get the exact name of the subdataset including the number after the :
The output filename needs to be separated by a blank.
