Yes, that looks right to me.  That will duplicate the partitioning from 
the disk before the pipe (| character) to the disk after the pipe. 
It's easiest to do it that way since the partitioning scheme that is 
used by BlueOnyx is not easily duplicated by using fdisk manually.

I also like Chuck's input on ensuring you have a good backup.  That's 
good advice no matter what the situation, but especially when you're 
working with potentially destructive disk operations.
