JBOD Mode: This mode concatenates a series of physical drives as a single large volume; Hard Drives are combined into a storage capacity that is equal to the sum of each of the physical hard drives. Switching to this mode will prompt to initialize and format the hard disks. If you choose to add a second hard disk at a later time, you will need to format the entire array of disks again. NOTE: All data previously stored on the hard drive will be lost! Please back up all data to a separate storage before continuing.
