How do I add a second disk to my DNS and convert from standard volume to RAID 1?

Pre-requisites:

- A second compatible disk for your NAS, preferably the same size as the existing disk
- The NAS already setup with the primary disk set as a standard volume (and not part of a previous RAID array)
- As with any procedure dealing with disks, ensure you have a backup before starting

Step 1 - Power off your NAS, and insert the second hard disk. Once inserted, power on your NAS, login and navigate to the Disk Management page (Management -> Disk Management -> Hard Drive Configuration.

Step 10 – If you did not enable auto-rebuild in step 6, you will need to manually rebuild the array now. To do so, navigate back to the “Hard Drive Configuration” page (Management -> Disk Management -> Hard Drive Configuration). Click “Manually Rebuild Now”

Step 11 – The NAS will correctly rebuild the array. Once complete, you will see the current volume is RAID 1.
