Copy EVERYTHING

[Hadders]

Hi all,
  I've been busy lately asking about RAID configs and the like and 
thanks to everyone who has provided feedback, it's been very helpful

So to recap.  I'll be using two SATA disks with the Intel RAID 
"hardware" set to RAID 0 so I can dual boot the system with XP.
I'll be reinstalling XP from scratch, as it's about time (some weird 
Windows behavior going on).

However, I plan on booting up with a Fedora Core disk 1, using "linux 
rescue" and working from there.
I assume that I will be able to see the SATA RAID container presented by 
the Intel chipset at this more basic level?
Assuming I can, I'll create the new partitions I want in the container 
and format them.
Then I'll mount the old partitions and run the following command I which 
got from an earlier email

 > cd /oldpart;  find . -xdev | cpio -padm /newpart

Is it really as easy as that to copy everything?

Thanks for any tips people can offer.
