Setting Up the Biggest Quadra

The LaCie Biggest Quadra is pre-configured at RAID 

level 5, but it may be re-configured. The RAID level is set 

using the RAID Level Switch Selectors on the rear panel of 

the LaCie Biggest Quadra. The RAID level selectors consist 

of two switches, with four possible switch position combina-

tions: RAID 0, 0 + 1, 5 and 5 + Hot Spare.

 The  LaCie  Biggest  Quadra  must 

be powered off to change the RAID level.

  In  the  event  that  the 

RAID level does not correspond to both the disk 

settings and the RAID Level Switch Selectors, the 

LCD  will  display  the  following  two  alternating 

messages:

1. “RAID level” 

“Unmatched”

2. “Current: Rx” (i.e. the current RAID level set-

tings of the installed disks) 

“Original: Rx” (i.e. the RAID level settings on 

the RAID Level Switch Selectors)

The RAID Level Switch Selectors are posi-

tioned to indicate a RAID 0 setting, but the 

disks were set earlier as a RAID 5 array, the 

LCD will display the following two alternating 

messages:

1. “RAID Level” 

“Unmatched”

2. “Current: R5” 

“Original: R0”

In this situation, the array will not function. 

There are two options:

1. Shut down the LaCie Biggest Quadra and 

re-position the RAID Level Switch Selectors 

to the previous RAID setting, in this case, 

RAID 5.

2. Re-insert the four drives, and re-create the 

array as a RAID 0 array. If there is any data on 

the disks, it will be lost during the initializa-

tion.

 If there is data on the array, chang-

ing the RAID level may lead to the loss of all of 

the data on the array.
