Re: Raid 0 (Mirroring) - Help?

That is what everything I found said about the controller... as a matter of
fact most everything recommends a completely seperate controller. I have had
this work at some of my customers sites with no problem, but I have two that
it just will not work at no matter what I do. (yes I even tried to mirror the
"D" drive)

I guess I will try to find a hardware IDE raid. That said will there be
anything I should look for when I install it other than disabling the onboard
controller in the server?
