There's lots to dd.  MSDOS partitions, for example, have a linked
list of logical partitions.  So, if you have, say, 3 logical
partitions, you must save:

(1) the main partition table
(2) the extended partitoin table
(3) the logical partition tables for partitions 6 and 7 (the
second 2 logical partitions)

Also, you might not want to interfere with boot loaders, which generally
share the same sectors (just, different parts of the sector ;-)
Of course, dd can handle that, but it's a little more tricky.
