Exactly so. dd makes a block for block, (or in the case of a disk, sector for sector) copy of the input file. Hence the need for something like ghost. Which BTW, originally started out as a sector copy tool but evolved into a utility that understands the filesystems it's copying and now actually makes a map of the disk and then compresses the data in a propriatory format. However, that ability allows it to move data between partitions of different sizes. It can even shrink them (as long as the destination is large enough to hold the data.)
