I have a RAID-1 configuration, and my RAID card died. I'm using drive 1 only until the new (identical) RAID card comes in. Can I just plug in the new card when it arrives, if some of the data on disk 1 has changed but disk 2 hasn't? Do I need to clone disk 1 onto disk 2? Or is there something else I need to do to refresh drive 2 when the new card arrives?
