When one HDD has errors ([1down]) in RAID5 mode, the data on the remaining HDDs can be read and recovery is possible. When two HDDs have errors ([2down]) in RAID6 mode, the data on the remaining HDDs can be read and recovery is possible. When any errors occur on an HDD, replace the effected HDD as soon as possible.

For details refer to the operating instructions for the extension unit. *Contact your dealer for information on replacing HDDs.

Important:
