Replacing Faulty HDD during RAID Operation

When one HDD errors ([1down]) in RAID5 mode, the data on the remaining HDDs can be read and recovery is possible.

When two HDDs errors ([2down]) in RAID6 mode, the data on the remaining HDDs can be read and recovery is possible.

Important:

Do not turn off the power until RAID is recovered. Data recovery may not be done normally when the power is turned off.

Note:

When errors (1down) occur in RAID6 mode, quickly execute error recovery.
