Win8 audit mode 2 drives

So I have just bought this new msi gt70 laptop, comes with a raid0, 2-128 gb ssd and a standard 750 gb secondary drive. the literature and naming of the drives ssd's c: os d: data. But in actuality does not, and just throws everything at the c: drive. What I would like to do is replace the d: with my own Seagate 750gb hybrid drive, could I image the disc across and not mess with the uefi ? new bios thingy ? Sorry just kinda learning on the fly here. Then I would like to enter the audit mode at oobe screen, but I am not a script writer, I had found a copy of script on seven forums and modified to my specifics for my win7 system. Can I use the same script with edits to win8 ?

Thanks for all thoughts
