Should work.

Should also have worked.

Ok, I have had once a problem with doing this too. I never found out why.
Can you do this by hand from your running FreeBSD installation?

I do not see when you wrote the MBR with bootable code.
bsdlabel -B will do the job.

Ok, you did it.
One other thing. I used either dd when copying the disk. Most of the time, I even use rsync. It takes forever but I can continue my normal work.

One question again. Does your kernel support SATA?
If not, it will not work. If it is a GENERIC kernel, it does.
