Hello I would love to build a raid0 system like yours with a third HD as back up but not in Raid.My specs are Giga EX38 DQ6 2 X WD YS 320G. 1 X WD YS 500G will run this internal(All Sata)I am slowly getting all the programmes I may need True Image 11,IMGBurn,Gparted.Waiting for win7 rc1 64 bit to arrive for general D/L. I want to run a dual boot with xp pro. I am a complete novice with raid/partitioning/dual booting. I have a lot of questions and I can not find any tutorials that cover the exact type of set up I am trying to achieve. Seems to be a lot of issues to satisfy and I really dont know where to begin. Can I go ahead with the XP install first ? OK set up the Raid 0 in bios , partition, install xp on first partition, install win7 64 on second, add third drive to next available Sata port,install TI, back up partitions.Need any info on restoring from TI to a HD in raid 0 array. Sorry to burden you with all my concerns but any help you could offer would be greatly appreciated.
