[FWTools] Problem with GeoTIFF created by gdal_translate

This is what I suspected. The gdalinfo output shows that you have only partial
georeferencing on the SID image : it has only a valid SRS, but no geotransform
matrix. By default, gdalinfo will consider that the left upper corner is at
(0,0) and the pixel size is 1. And -co TFW=YES will not produce anything as the
geotransform matrix is not set.
I see that near your .sid you have a .sdw and a .sid.aux.xml file. The later
seems to have been produced by GDAL ? I would try to remove one or both and see
if things improve. They are maybe conflicting with the internal georeferencing
of the .sid
