2. If there is not already an internal volume (storage area), click Storage
from the navigation panel, and then click Create an Internal Volume. If
your hard drive already has a volume that you want to use, skip to section
6. If you want to delete an existing volume, see the Storage Screens
chapter in the User's Guide.
Creating a volume formats the hard drives. All data will
be lost.
3. If you have two hard disks installed, select a disk configuration.
• JBOD (maximum data storage space)
Uses the whole storage capacity of each disk, even if there are two
hard disks with different storage capacities. With two hard disks, you
can create two volumes (one for each disk) so a failure of one hard
disk should not affect the other. With two hard disks in a single JBOD
volume, you lose all the data on both disks if one disk fails.
• RAID 0 (not recommended)
Has the highest write speeds but if one disk fails, you lose all the
data on both disks. Only use RAID 0 for non-critical data requiring
high write speeds (like video, graphics, and games). Total data
storage space is limited to twice the capacity of the smallest disk.
