You probably don't have a FreeBSD partition on wd0.  This is how I would do it.
1) disklabel -B wd1  # This puts the boot block on the booting disk.
2) Install a dos boot manager on wd0 which I assume is a dos drive.
I use bteasy from the tools dir on FreeBSD.org.

When you install the boot manager bteasy, let it write itself to wd0 but
not wd1.  bteasy will then allow you select the second drive and will
use the native active partition and boot.  If FreeBSD uses the whole disk,
writing bteasy or most other managers to that disk will blow away the boot
blocks.
