Hi,

I believe the problem is that you do not escape the double quotes
when passing them via the commandline.  It is important that the
double quotes make it into GDALOpen() so that the D: will be treated
as part of the one path token when things are parsed.

So, if you were to specify things on the commandline I think you would
need to do it as:

  gdalinfo HDF4_EOS:EOS_SWATH:\"D:\data\aa.hdf\":mod35:Scan_Start_Time

The exact escaping mechanisms and requirements may vary depending on
the command shell used.  What is important is that after all shell
processing the double quotes still remain around the path portion
inside the call to GDALOpen.

Best regards,
