Hot Swapping to Migrate from Standard Mode to RAID 1

You can add a second hard drive and migrate it from Standard mode to RAID 1 without shutting down the DNS-320L. Standard Mode doesn't offer
any redundancy and security of data. It is best then to migrate from Standard Mode to RAID 1. To do this follow these instructions:
Step 1 - Insert a second hard drive into the DNS-320L.
Step 2 - Check the second HDD LED status. If the HDD LED is
blinking, please wait for the blinking to stop before proceeding.
