How to recover RAID-5 volume when a member of it has failed? Repair RAID-5 volume by Windows snap-in disk management or EaseUS Partition Master.

As one type of dynamic volumes, the 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 of 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.

How to recover and repair a RAID-5 volume

The highlight of the RAID-5 volume is that the data of the failed member can be reconstructed from the remaining members. Therefore, even if you are strapped in a situation that one member of RAID-5 volume fails, there is a way to have the damaged member back.

Both Disk Management snap-in and EaseUS Partition Master can repair RAID-5 volume by reconstructing the data of the failed member on another disk.

Recover a RAID-5 volume by disk management:

Right click computer > choose Manage > click disk management;

Then right-click the RAID-5 volume and choose "Repair volume" in the down-drop menu.

There must be a new area of free space that is the same size as or larger than the other members of the RAID-5 volume at the disk where the repaired member will reside on. If there is no such available space, you must first connect a new hard disk to the computer before repairing.
