RAID 10 Recovery After Failed Rebuild on Microsoft Windows Server

A business client experienced a RAID 10 rebuild failure on their Microsoft Windows Server, leading to severe data corruption across the array. The server contained critical virtualised environments (VHDX virtual file systems) and had no backup available, making data recovery the only viable option.

Additionally, the server continuously displayed SMART errors, indicating potential hardware degradation and further risk of data loss. With business operations at a standstill, immediate intervention was required to recover the data and restore functionality.

Our Expertise in RAID 10 & Virtualized System Recovery

With 25 years of experience, our team specialises in advanced RAID recovery, including:
Rebuilding failed RAID 10 configurations
Recovering corrupted VHDX virtual machine files
Using forensic data recovery techniques to reconstruct RAID file fragments

Diagnosis & Recovery Process

Upon receiving the RAID 10 system, our engineers performed an in-depth hardware and software analysis to determine the extent of the failure. The key issues identified were:

  • RAID 10 Rebuild Failure – The rebuilding process resulted in data inconsistency, corrupting file structures across mirrored disks.
  • SMART Errors – The server flagged disk health issues, with some drives reporting bad sectors and read errors.
  • Corrupted VHDX Virtual Machines – The Windows Hyper-V environment failed to load due to missing or fragmented VHDX files.
  • No Backup Available – Making direct RAID reconstruction and forensic recovery the only solution.

To recover the client’s critical data, we implemented a multi-step RAID and VHDX recovery strategy:

Step 1: Disk Imaging & SMART Error Analysis

  • Cloned all RAID disks sector-by-sector to avoid further damage.
  • Performed a detailed SMART diagnostic to isolate failing drives and extract healthy data.

Step 2: Advanced RAID 10 Reconstruction

  • Repaired the RAID metadata and parity structure to correct inconsistencies.
  • Used advanced forensic techniques to manually reconstruct fragmented RAID file systems.

Step 3: VHDX Virtual Machine Recovery

  • Extracted and reassembled corrupted VHDX files from the RAID array.
  • Repaired missing VM configurations and metadata to ensure full virtual machine functionality.

Step 4: Data Integrity Verification & System Restoration

  • Validated recovered data integrity to ensure all critical files were accessible.
  • Migrated the restored VHDX virtual machines to a new RAID 10 array, ensuring future stability.

The Result

We successfully recovered 99% of the client’s critical business data, including their virtualised work environment. The business was able to resume full operations within 72 hours, preventing catastrophic data loss and minimizing downtime.
