RAID issues - disk showing as offline

Hi, we have a dell xps desktop machine with 4 disks, 2 are setup as raid 0 with no issues, the other 2 were set up as raid 1 via bios. the raid setup in bios looks perfect and is the same when compared to othr machines in the office.

I had to add a new disk after a failure. When I view through windows disk management - i expected to see only 2 entries "disk 0 and disk 1) but it is showing 3, and the third is offline. I have googled and i think it may have something to do with the disks having the same "Disk ID". I have no idea how this would occur. Screenshots show a correct configured machine and the machine I am having the issue with.

I've no real expertise with the Dell XPS, but don't you have to use the Intel Matrix Storage Manager to add the new hard drive to the RAID?

You need to manually add the new disk in your raid controller.

PS: I see you're using a 750GB disk to mirror one hdd with 150GB capacity. You do realize you're going to lose 500GB, correct?

Thats not correct Dan. In the screenshot with the problem we have 2 80GB disks in raid 0 so that is disk 1 showing 147.15GB

The other 2 disks are showing as 931.51GB and 698.64GB, this should be raid 1 with a total disk size of 698.64GB losing about 200GB which I am aware of and happy about.

So, this raid setup in dell is not plug and play or hot swappable???

OK, I thought the first disk was the mirror you broke :)

I don't know with what Raid controller your particular station uses (no model in your post), but for most low end controllers you have to manually add the new hdd after failure/swap.
