I have experienced this problem before myself.
Basically, I had to manually take a look at the partition sizes
of source and partition the destination the same way.
The caveat was also that the source partition table area was not
the same as the destination's :(
So that wreaked havoc with what the firmware of the destination
thought was the partitioning scheme AFTER the dd from src to dest.
Someone showed me how to use the binary editor to fix the destination's
partition information. Unfortunately, I lost much email after drive crash
and replacement.
