4.1.1. RAID 5 ■
CAUTION: In a RAID 5 array, in the event
that a disk needs to be replaced, always replace the
failed disk with the LaCie Biggest Quadra’s power
on. Do not turn the LaCie Biggest Quadra’s power
off; doing so may lead to the loss of the data on
the array.
ImpOrTANT INfO: In a RAID 5 + Hot
Spare array, the disk in the top drive bay is desig-
nated as the Hot Spare (the default setting), and
the Disk Status Indicator will light in amber to
indicate this configuration.
Power off the LaCie Biggest Quadra.
Move switch 1 of the RAID Level Switch Selectors
to the OFF position. Move switch 2 of the RAID
Level Switch Selectors to the ON position.

4.1.2. RAID 5 + Hot Spare ■
TeChNICAl NOTe: In the initial configura-
tion of a RAID 5 + Hot Spare array, the top drive
bay (Drive Bay 1) is the default Hot Spare (the Disk
Status Indicator will be amber). In the event that a
disk fails, the Hot Spare position will change.
For example, if the disk in Drive Bay 3 fails, then
the Hot Spare disk in Drive Bay 1 will be re-built
and will no longer be the Hot Spare. Instead,
when you place a new disk in Drive Bay 3, it will
become the new Hot Spare, and will be indicated
by the amber Disk Status Indicator.
