CAUTION:
IEI disclaims any responsibility for product damage/malfunction or data
loss/recovery due to misuse or improper installation of hard disks in any
occasions for any reasons.
Note that if a hard drive (new or used) which has never been installed on the
NAS before it is installed, the hard drive will be formatted and partitioned
automatically and all the disk data will be cleared.
3.5 RAID Recovery
The NAS supports exclusive RAID recovery technology to recover a failed RAID disk
volume from unintentional disconnection or removal of the hard drives from the system.
Using the RAID recovery, users can recover an inactive RAID 1, RAID 5, or RAID 6
volume to degraded mode, or an inactive RAID 0 and JBOD configuration to normal.
Disk volume Supports RAID recovery Maximum number of disk
removal allowed
Single No -
JBOD Yes 1 or more
RAID 0 Yes 1 or more
RAID 1 Yes 1 or 2
RAID 5 Yes 2 or more
RAID 6 Yes 3 or more
RAID 10 No -
If the volume status is not active, users can install the same hard drives back to the same
slots of the NAS. Then click “RECOVER” on the “Disk Management”  “Volume
Management” page. Wait for about 60 seconds for the process to complete. When
finished, the data can be accessed.
