If you got this from the SSEC archive, then these are McIDAS
grids not GRIB files.  You would need the raw GRIB data for
gribtocdl to work.  If you need the GRIB data, please send
a message to address@hidden (you need to subscribe
first) requesting the type of data you want (ETA, AVN, etc)
and the dates for the raw data.

If you are using one of the standard GRIB data supported under
gribtonc (i.e., AVN, ETA), you should just use the CDL's that
come with gribtonc instead of running gribtocdl.
