Thanks, Fernando. But I did ruin the MBR so that I had to fix it using my XP disc with the fixmbr command or the other one I don't remember. The fixboot command I think. More questions... what to expect when RAID is active? I heard I'd get more from RAID than AHCI. Is that right? If I'm not changing anything, I mean the drives and cables are gonna be as it is now, is there gonna be a difference except the enhanced features of AHCI? Now I'm using c: as windows, d: as games on the SATA drive, and e: as my documents on the PATA drive. Could I use the exact same partition config?
