Having created problems for myself by doing something similar in the
past I'd be wary of using dd for this,

the relevant thread in comp.unix.bsd.freebsd.misc.
The safe approach would be to use fdisk to create the desired slices on
the new disk, use bsdlabel to partition the FreeBSD slice and then use
dump|restore to copy the data.
You should be able to copy your Windows partition with DriveImage XML,
free for private use from <http://www.runtime.org/driveimage-xml.htm>
