If the drives are *exactly* the same, you can use dd from one raw
device to the other (dd <args> -if=/dev/rsd0c -of=/dev/rsd1c) (those
are from memory, so excuse if I messed up the syntax slightly).
If they aren't identical, you will need to put a disklabel on the new
drive, newfs its filesystems, then copy the files. The most common
way to copy all the data intact is:
cd /olddir ; tar -cplf . | ( cd /newdir ; tar -xp --unlink --file - )
This will not traverse a mount point (which is what you want), so
you'll have to do / and /usr separately (and any other things you have
mounted that you want to copy.
