raid problem

ok heres the thing i dont know much about raid so i will put as much as i know i have 2 hdd's hooked up to mobo and 2 more hooked up to raid card windows xp cant find the 2 hdd's on the raid card can anyone tell me how to do this and to make them all 4 work as one big drive i guess i need help setting them up i dont even know what info to give you guys on this one. so just ask and i will tell

 

can you give us some hints? is this a new system you just built, or did you just pop in a card and hooked up 2 more drives? i also don't know much about raid, but i know a tad about helping, but you need to tell us SOMETHING.

 

never mind i got it working
