5.7.2. 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 possible options provided in the recovery window. Multiple possible RAIDs are constructed according to the combination of parameter options provided by the user. The user can choose one of them. After the RAID is rebuilt, user can perform a scan and recovery on the RAID volumes.
