library(rgdal)

Gdalinfo("")

 Error: could not find function "Gdalinfo"
 > GDALinfo("")
  Error in .local(.Object, ...) : 
 `' not recognised as a supported file format.

            > GDALinfo("" ,returnCategoryNames=FALSE)

             Error in .local(.Object, ...) : 
     `' not recognised as a supported file format.

        > a=readGDAL("")

        Error in .local(.Object, ...) : 
      `' not recognised as a supported file format.

a=readGDAL("file.hdf")

       Error in .local(.Object, ...) : 
      `file.hdf' not recognised as a supported file format.

GDALinfo(fname="file.hdf")

       Error in .local(.Object, ...) : 
     `f' does not exist in the file system,

and is not recognised as a supported dataset name. 5

      > GDALinfo(fname="file.hdf")

   Error in .local(.Object, ...) : 
      `file.hdf' not recognised as a supported file format.

  • Download the file and check whether the size in the ftp directory listing matches the size on your local system. As for checksumming, usually running through `gdalinfo -checksum` is enough. – Deer Hunter May 14 '13 at 09:11

Which HDF library for R are using?
The files you try to open are HDF4 files and not HDF5.
You can use HDF5View to open the files.
