Learn how to recover data from an Unraid server when the array is damaged, the configuration is lost, or one or two data drives are missing.
In this video, we demonstrate how to recover files from Unraid Single Parity and Dual Parity arrays using Hetman RAID Recovery. You’ll see how to connect the original drives to a Windows, Linux, or macOS computer, create sector-by-sector disk images, scan individual XFS data disks, determine the correct disk offset, and virtually reconstruct a damaged Unraid array.
We’ll cover:
• How Unraid Single and Dual Parity arrays work
• How to connect Unraid data and parity disks to a PC
• How to create and mount disk images
• How to recover files directly from healthy XFS data disks
• How to find the correct XFS Offset using the HEX Editor
• How to reconstruct a Single Parity array with one missing disk
• How to reconstruct a Dual Parity array with two missing disks
• How to detect the original disk order automatically
• How to recover files from the reconstructed array safely
Because Unraid stores complete files on individual data disks instead of striping them across the entire array, data can often be recovered directly from surviving disks. When drives are missing, parity information can be used to virtually reconstruct the lost data.
This guide is useful for Unraid systems affected by disk failure, server hardware failure, damaged USB boot drives, lost array configuration, or changed disk identifiers after replacing an HBA or storage controller.
