I followed toms guide for enabling RAID 5 on my XP Pro Machine and I still can't get it to show the RAID5 option enabled. I have 3 extra 200 gig disk in right now. One has all my stuff on it and will be my temp storage while I make the array. The other 2 are just sitting. before I go and buy the last disk I need, I tried to get the hack to work and see if the option was avaiable. The option is there but is disabled. for anyone that has done this yet. do I need to have all three disk empty and dynamic for the option to not be grayed out? or is it there before the hack?
