I've had a harddrive failure on a computer running 4.2-S.  A test
program from the manufacturer (it's an IBM DeskStar 13G), found bad
blocks.

It's a root disk for my FreeBSD installation, and it freezes once in a
while, reporting write failures to console.  I have a spare disk, wich
is a 6.4G.  This is more than enough to back up the data from the 13G
one, but if I understand correctly, I can't use dump for that, since
all the partitions are not going to fit in.

Would anyone be so kind as to tell me how I can create a working copy
of my current installation?  I would like to save all data from /,
/var, /usr and /home.  I think I can just partition the disk using
/stand/sysinstall and cp -Rp the files to it.  But how would I make it
bootable?  And also, would cp -Rp work on kernel files and /boot
directory?

I'm under a bit of a pressure, since I have to babysit the system
(because it hangs once every hour).  Although any kind of hints are
very welcome, I'd really appreciate something other than a RTFM
response. ;^)  I'll RTFM later, I promiss.

The failed drive is ad0; drive ad3 is a clean 6.4 drive, which I want
to use as a replacement for ad0 while it is being exchanged.
