I never used any other operating system on a machine with FreeBSD. So, my comments could be off.

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.

This works always but copying properly the old disk must also work.

One question again. Does your kernel support SATA?

If not, it will not work. If it is a GENERIC kernel, it does.
