e LaCie Biggest Quadra
is not recognized by the
host computer.
Ensure that the interface cable (either FireWire 800 or Hi-Speed USB 2.0) is securely attached to
both the LaCie Biggest Quadra and the host computer. Check the LCD Display of the LaCie Biggest
Quadra for error messages.
I was creating a RAID 5 ar-
ray, and a disk failed. What
should I do?
Replace the failed disk with another disk of equal or greater capacity. e array will re-initialize when
the failed disk is replaced and the process is restarted.
I only have two or three
disks. Can I still create a
RAID array?
e LaCie Biggest Quadra cannot create an array from just two disks. If you only have three disks,
you can only create a RAID 5 + Hot Spare array. e three disks must be installed in the bottom three
Drive Bays, with the top Drive Bay (the Hot Spare location) empty.
e LCD Display reads
“unmatched.”
e RAID Level Selector Switch is not set to the level of the existing array. 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 settings of the installed disks)
“Original: Rx” (i.e. the RAID level settings on the RAID Level Switch Selectors)
Example:
e RAID Level Switch Selectors are positioned 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. ere 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 initialization.
