5.8.2. Building RAID When Parameters are Unknown
To build RAID using Stellar Data Recovery, the user must preferably know the disk order, start sector of RAID in each disk, stripe/block size, parity repetition/delay, and parity order. If any of the RAID parameters are not known, the user can select the "Auto-detect RAID parameters" provided in the recovery window. This option automatically configures the optimal RAID settings for quick recovery, rebuilding the RAID in most cases while minimizing data loss and reducing manual intervention.
To build RAID when parameters are unknown:
-
Run Stellar Data Recovery.
-
From the side panel, under Other Recovery Options, Select
RAID Recovery option.
-
Click Next.
-
The RAID Reconstruction window is displayed. All the RAID drives and a missing drive are shown in ‘Move disks to Reconstruct RAID‘ section.
-
In the ‘Move disks to Reconstruct RAID‘ section, click on a RAID hard disk and then click
Repeat this till all the RAID disks are shown in the ‘Set the disk order as per RAID config‘ section.

In Set the disk order as per RAID config‘ section, click on a hard disk and then click
or 
to change its order. Repeat this till all the drives are in the correct order. Click the block under RAID start sector to type the starting sector. -
If you're unsure of the parameters, select the "Auto-detect RAID parameters" radio button. This option automatically configures the optimal RAID settings for quick recovery, rebuilding the RAID in most cases while minimizing data loss and reducing manual intervention.
Note: Ensure at least 3 disks are selected to build the RAID. Add a 'Missing' disk to replace any failed disk.
-
Click
. The recovered RAID is shown. -
If you have used the "Auto-detect RAID parameters" option for one or more of the RAID parameters, a list of probable RAIDs are constructed and shown in a list. RAID information is also shown. Select one of the RAIDs according to its score and click the Show Volume List button.
