 Why?  What good are these disks if they don't have
 the most basic of commands?

Only live systems offer more than the holographic shell
when booted properly. FreeSBIE has been a very good live
system in the past, but the current installers also allow
you to drop into a working shell environment at a very
early stage (from within bsdinstall).

This dialog should bring you into a working shell. I've
been using it myself for disk initialization with a
FreeBSD 9.1 CD.

Thanks, Polytropon.  I couldn't get FrieSBIE to work.
Hung up.  Used mfsBSD instead.  

Had to use 8.X because 9.X hangs.  I think it has something
to do with my PS2 mouse and keyboard.





 Trying to clone a hard disk that has an number
 of bad sectors.  Trying to save most of my data.

A good approach. If possible, try to obtain a 1:1 copy
of the disk (or partition) and work with that. Check
the mailing list archives for further inspiration.

The emergency holographic shell was always very limited.  I suspect a 
path thing, with it looking for commands on the installed system.  Old 
bare-bones tricks like echo * help.

Use mfsBSD: http://mfsbsd.vx.sk/

Thanks, Warren.  MFSBSD worked for me.

Had to use 8.X because 9.X hangs.  I think it has something
to do with my PS2 mouse and keyboard.  9.X still only seems
to work with USB peripherals--or is something else going on?

I was a bit skittish using recoverdisk because I couldn't
find any explicit notation about source and target.

# clone a hard disk
 recoverdisk /dev/ad3 /dev/ad4

As it turns out, the first argument is the source and the
second is the target, as one might intuitively guess.  However,
I've been burned before by guesses, so I hope someone will
update the man pages to make this obvious.

It says

 recoverdisk [-b bigsize] [-r readlist] [-s interval] [-w writelist]
 source [destination]

That seems pretty clear, although the text does not really explain what 
happens if the optional destination is not given.  Output to stdout 
would be the standard expectation.

It's a rather old project, and as far as I know, it isn't
being continued anymore. It should still support at least
the CLI mode for most computers... (I have to admit that
I'm still using it, but usually on _older_ computers where
it often works flawlessly.)

Good choice. :-)

Can't imagine _that_ as a cause of OS hangs, but it might
still be a hardware compatibility or configuration problem.
If v8 works for you - no problem, it's still supported.
