How to recover a RAID-5 volume with disk management software?

As one type of dynamic volumes, RAID-5 volume is featured by dedicating the equivalent of the space of one disk in the RAID-5 volume for storing the parity stripes and these parity stripes are distributed across all the disks in the group.

If a member of a RAID-5 volume fails because some kind of reason, it becomes an orphan and the operating system determines that it can no longer be used and directs reading and writing all new data to the remaining members of the fault-tolerant volume.
