That's an interesting approach to upgrading the drives. I hadn't thought of 
that. I have a pair of 250G drives that are close to capacity. I bought some
1TB drives to replace my current drives.

Have other people tried this approach for moving to bigger drives in a RAID 
1 configuration? Is it possible to use gparted to change the partition sizes 
after rebuild process or does it clone information that makes the system 
think the new drives are only as large as the original drives?
