Maybe you should explain what you want the final configuration to be. Is the RAID still going to be active, etc.

I do not run a RAID so I can't help much, except if you are going to run a RAID, have a driver ready and it you are not, you will need to change it in the bios. I don't even know how to un-RAID----

Would RAID redundancy really be necessary with Win7 Backup Imaging? My external is plugged in and always backing drive image and files when Win7 idle.
