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.
