I've two "WD Caviar Green WD10EADS 1 TB" HDDs. Yet I'm just using the one of them, but would like to setup a RAID 1 without reinstalling my Windows 7 64-bit. This article looks interesting, but I have some questions before staring:
1. I'm having a Asus P6T Deluxe V2 motherboard. Should I use the article for ICH8(R) or ICH9(R) southbridge?
2. When I change from SATA to RAID 1 in my BIOS, would the controller my itself copy all the data from the original HD to the new one? Or should I do a clone before changing from SATA to RAID in BIOS?
3. Finally, is there anything else to know?

Generally it looks quite simple.
Thanks for your answers!
