Thank you Jon.
You're correct I over-wrote the entire disk ( all sectors) with zeros. Are you saying if I installed FreeBSD SW it would have protected the boot sector ( drive label) or are you saying I should have use the FreeBSD to wipe the drive and it would have not erase the drive label?

You wish to run FreeBSD on a computer with a completely wiped disk? If
so, you would have to install FreeBSD from the beginning. There is
unlikely to be anything useful on the disk if you used a disk wipe
feature of a disk diagnostic program. In other words, it's likely that
there's nothing there to repair.
If this isn't what you mean, could you please supply more information on
what you mean by "wipe?" I'm taking it to mean overwriting every part
of the disk at least once to make data recovery essentially impossible.
