Error recovery of the hard disk drive (when operating in the RAID mode) If a hard disk drive failure occurs in the RAID 5 or RAID 6 mode, the error display will appear as shown in the following table. In the RAID 5 mode, it is possible to read data on the other hard disk drives and recover data even when a single hard disk drive becomes faulty (1 down). In the RAID 6 mode, it is possible to read data on the other hard disk drives and recover data even when 2 hard disk drives become faulty (2 down). When the hard disk drive becomes faulty (down), replace it immediately. Refer to the operating instructions of the extension unit. * Contact your dealer about replacement of HDD units. Important: • In the RAID 5 mode: If 2 or more hard disk drives become faulty (2 down) or when another hard disk drive becomes faulty during the data recov- ery, it is impossible to recover data. • In the RAID 6 mode: If 3 or more hard disk drives become faulty (3 down) or when another hard disk drive becomes faulty during the data recov- ery, it is impossible to recover data.
