Hello,

as far as I can tell from your data, your rasterfile has a problem with 
its projection: The associated .tfw file you put online had the wrong 
name (the raster is named ST.tif, therefore the .tfw - file has to be 
named ST.tfw).

So two questions to dig further:
Is it the right .tfw file for that raster?

And in which projection is the raster - in the .tfw file are just 
numbers, from which it is hard to guess for me, to which coordinate 
system they belong to... (UTM or a national grid...)

Maybe for a little background, a look on wikipedia...
