The problem with this is that you have to copy onto a mounted filesystem.
But if you mount the disk, it will be found by find, and you'll have an
infinite loop (you'll see that that disk isn't nearly as big as you though :-).

So what you want to do is this:
1) Make sure the new disk (and any others, if you have any) is UNmounted.
2) cd / ; find . -depth -print >tmp/files	# (Make the list of files)
   mount /mnt /dev/dsk/c1d0s0			# mount your new disk
   cpio -idm /mnt </tmp/files			# move over files

That's it. BTW, the -m flag to cpio is VERY important. Without it all the
files will take on the current date. You _don't_ want this.
