[Cialug] Moving from 3ware RAID to standard disk

[Nathan C. Smith]

I have a machine running on a 3ware PATA mirror that I would like to move to just a standard SATA disk.  I have a running configuration I want to keep, I'd just like to run it faster on a newer machine.   I expect that if I just dd the disk from the 3ware machine to another disk I will would up with something that will not boot.  The machine in question is Debian Squeeze.  See my fdisk-l output below.

Has anyone done something like this before that can outline a procedure I might follow to accomplish what I want to do?   I suppose I could try dd and then a rescue disk, but I was hoping for a better approach or more obvious approach.  Maybe I am overthinking the situation?

Thank you.
