Christiaan,

Are you working programmatically or as a user with end-user tools like gdalinfo
and gdal_translate?

For an end user, one would normally run gdalinfo against the file/dataset and
see the reported subdataset names.  Then run gdalinfo or gdal_translate against
the desired subdataset name.

Scripts/applications operate similarly, fetching the subdataset names from
metadata.

You may find it helpful to read the section titled "SUBDATASETS Domain" in
this doc:
