It should not prevent your machine from booting, though, why? because the array is still functional as only 1 drive failed, maybe something else happened to your system. To see if if this is the case, I'm gonna try it right now with my 7500-8 controller. Perhaps someone on the list can confirm this. I believe I tried this once with Mylex Accelerated serries and it worked as I describe above. -Simon On Thu, 02 Oct 2003 09:28:50 -0600, Cassidy B.
