dd for Dummies

Howdie. I need to copy the first partition of one disk (lets call it
hdb1) to the first partition (hdc1) on another. The partitions are
exactly the same size and I was hopping that one of you might check my
command line instructions before I blew anything up. Yes, dd scares the
heck out of me because of it's power...

$dd if=/dev/hdb1 of=/dev/hdc1

Do I need any options?
