RAID
Before you change the RAID mode of the LaCie
2big, familiarize yourself with the 2big’s RAID modes.
See section
3.1. About 2big Dual RAID Modes
.
ImpOrTANT INfO:
Changing the RAID mode de-
stroys data stored on the LaCie 2big. If you have saved
data on the drives, back up data before following these
steps.
CAUTION:
Disk drives must be inserted correctly in
the 2big before configuration can be changed.
To change the RAID mode:
If there is data on the 2big you want to save, back it
1.
up to another device.
Unmount or safely remove the 2big volumes from
2.
your computer.
ImpOrTANT INfO:
Do not turn off the 2big. The
2big must be on when the RAID mode is changed.
Insert the small end of the included 2-in1 tool into
3.
the groove on the rotary switch and turn the screw-
driver to the left or right to select a different mode.
Remove the 2-in-1 tool from the rotary switch and
4.
use it to depress the confirm button. The two drive
status LEDs blink quickly to confirm the RAID
mode change.
ImpOrTANT INfO:
You must partition the disk
drives after changing the storage policy configuration.
See section
3.3. Partitioning the LaCie 2big Disks
.
3.2. Changing the RAID Mode
CAUTION:
Your LaCie 2big comes preconfig-
ured in Fast (RAID 0) mode. Fast mode allows
access to the whole storage capacity but does not
provide any security. If a drive fails, all data will
be lost. If you are concerned about data security,
LaCie highly recommends a RAID 1 (Safe 100,
Safe 50 or Safe 33) configuration. See section
3.1. About 2big Dual RAID Modes
, for more in-
formation.
