Explanation

In order to restore the RAID-5 volume, Mark will have to replace the failed drive with a new one, use Disk Management, select a new area of free space, and then regenerate the volume. When a member of a mirrored volume or a RAID-5 volume fails, it becomes an orphan. Data for the orphaned member can be regenerated from the remaining members. A new area of free space that is of the same size or larger than the other members of the RAID-5 volume should be selected in Disk Management and then the data should be regenerated. The fault-tolerance driver reads the information from the stripes on the other member disks, and then re-creates the data of the missing member and writes it to the new member on restarting the computer. The volume must be locked by the operating system to regenerate a RAID-5 volume. All network connections to the volume will be lost when a volume is regenerated.
