Upgrading From Standard Mode To Raid 1 - D-Link DNS-320L User Manual

Section 4 - Configuration

Upgrading from Standard Mode to RAID 1

Standard Mode doesn't offer any redundancy or security of data. If, after formatting for Standard Mode you find that you require
the additional features of RAID 1, it is best then to migrate from Standard Mode to RAID 1. To do this, follow these instructions:
Insert a second hard drive into the DNS-320L as per the instructions for the
initial installation. The existing hard drive should be the volume which you
wish to create a mirror of using the RAID 1 format.
Replace the top cover and restart the DNS-320L.
