	The 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. 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 initialization.
