I had issues with HDD failure and standard backups were not ideal so I am trying Raid for the first time. I considered a controller card but my motherboard has raid built in.
Go to bios (del), advanced>components> change to RAID for IDE SATA. Can be under Storage Configurations. Save and exit.
The shortcut is ctrl + i during boot. This will bring up the RAID config. Create new raid, raid level 1 mirror) select disks, create volume.
Need to start with 2 blank drives.
