Automatic RAID 5 recovery

In addition to manual RAID 5 recovery, there is always an option to try a special tool to recover RAID configuration parameters. There are both paid and free RAID recovery software.

To recover RAID 5 you need to determine the following parameters:

  • block size,
  • disk order,
  • start offset,
  • parity position and rotation,
  • first delay and parity delay, for RAID 5 with delayed parity,
  • how spare blocks are located on the array, for RAID 5E and RAID 5EE.

As one can see, it is required to recover a lot of parameters. Manual RAID recovery is a rather complicated task taking a very long time. Typically, RAID recovery tools are quite good at this task - see RAID recovery software comparison for more detail. Thus, to recover RAID 5 parameters automatically you need to:

  1. Disconnect member disks from the controller and connect them to the PC's motherboard directly.
  2. Launch a RAID recovery tool.
  3. Either feed the recovered configuration back to the controller, or use the recovered configuration along with data recovery software.
