HARD DISK EXPANSION: SINGLE-DISK AND
UNPROTECTED VOLUMES
Review the information below before attempting to add hard disks to a single-disk or unprotected volume.
Important info on NAS Backup: It is recommended that all users back up data to DAS or another NAS as
further protection against disk failure or secondary points of failure (e.g. hardware, network, etc.). See
Backup Jobs for details.
REMOVING HEALTHY DISKS FROM AN UNPROTECTED VOLUME
An unprotected volume can be:
SimplyRAID single-disk
RAID 1 single-disk
JBOD
RAID 0
Removing a healthy hard disk from an unprotected volume while the LaCie 5big NAS Pro is powered
on will delete all of the volume's data. While removing healthy disks is not recommended, you can avoid
losing data by shutting down the LaCie NAS first. Return the hard drives to their proper bays before powering on
the LaCie NAS.
Additionally, powering on the LaCie 5big NAS Pro with a missing disk in an unprotected volume will break its
RAID and all data will be lost.
