I have a Raid-1 with two 67.75 GB drives mirrored for the C: of 12GB and the E: of 55.6GB. I am running out of space on C: and need a solution. I have a 300GB drive I could add to the Raid-1 but am not sure if that is possible. This is a working production server and would like a solution that will not cause data loss if possible. Any assistance would be greatly appreciated.
