Ive been searching all over and cant find anything on this subject. I have a Raid 5 configured in Server 2003 using 3 1.5Tb drives, I have a 4th drive I want to add as a hot spare and I would need to use the spare automatically if one of the drives fail. Is this even possible in a windows raid?

This question came from our site for professional and enthusiast programmers.

When you say Windows RAID, are you talking about the software RAID? – Zoredache Sep 12 '11 at 16:24
Yes, Im using the raid 5 function built into Windows – Brian Tacker Sep 12 '11 at 16:33

Hot-spare and hot-swap drives are features of hardware RAID controllers

So there's no way to designate a 4th drive as a spare for it to rebuild on? – Brian Tacker Sep 12 '11 at 16:22
Replace failed disk with your 4th and rebuild. – Sergey Sep 12 '11 at 16:36
