I have a Dell 2950 server that has integrated RAID 6/i. I am running Windows Server 2008 R2. I have two SAS drives installed and am using them for my base OS and VM's. I needed to add space but since it's just a DEV machine, I thought I should just go with a SATA drive (cheaper for more space). I understand it cannot be part of the RAID, but can it be used outside the RAID as an additional data drive? Second question is, if I disable RAID, will I lose all my data on the two drives that are already there?
I am asking these questions because I cannot get the drive to show up in Disk Management. I also tried to add a external USB drive, and it also does not show up in Disk Management. I am assuming that RAID is on and either cannot be added as a third drive since they are not in the RAID? Any feedback and/or solutions would be helpful.
