I can only tell you what happened with dd if=/dev/hda of=/dev/hdc:
All partitions (ext3, swap, vfat) were copied with their respective
original size preserved.

dd'ing partionwise into a bigger partition (eg. dd if=/dev/hda1 
of=/dev/hdc2) still only replicates the original filesystem's size - 
don't know about changing that with any dd options.
