Just a comment: There are some grib files generated by SPRING that are 
not compatible with the GRIB driver. It might be a version issue GRIB1, 
GRIB2 or something. Ex.:

C:\Data\SpringDB\SP\SPaulo>gdalinfo I000355.grb
ERROR 4: `I000355.grb' not recognised as a supported file format.

gdalinfo failed - unable to open 'I000355.grb'.
