TerraMaster NAS Data Recovery After RAID 0 Failure Due to Power Surge

A client using a TerraMaster NAS with four drives configured in RAID 0 experienced a catastrophic failure after a power surge. The key issues included:

  • Two of the four RAID 0 drives failed, making the RAID array inaccessible.
  • The NAS was unable to recognise the RAID configuration or allow access to stored data.
  • No redundancy in RAID 0, meaning all data was lost unless the failed drives could be recovered.

With critical business and personal data stored on the NAS, the client urgently needed data recovery services to retrieve important files.

Our Expertise in RAID 0 & NAS Data Recovery

With 25 years of experience, our team specializes in:
Recovering RAID 0 arrays after multi-drive failures
Rebuilding damaged NAS systems after power surges
Forensic data recovery techniques for fragmented RAID data

Diagnosis & Recovery Process

Upon receiving the TerraMaster NAS, our engineers conducted a detailed forensic analysis. The key findings included:

  • Two Drives Were Completely Unresponsive – Suggesting electrical failure from the power surge.
  • RAID 0 Configuration Was Compromised – Since RAID 0 stripes data across all drives, the failure of two disks meant severe data fragmentation.
  • NAS Controller Was Functional – Indicating that the issue was at the disk level rather than the NAS system.

To successfully recover the client’s critical data, we implemented a multi-step RAID 0 forensic recovery strategy:

Step 1: Drive Imaging & Power Surge Damage Assessment

  • Created sector-by-sector forensic images of the two functional drives to prevent further corruption.
  • Opened the two failed drives in a cleanroom environment to assess internal damage.
  • Repaired PCB damage and replaced damaged controller chips to restore drive functionality.

Step 2: RAID 0 Stripe Analysis & Data Reconstruction

  • Used forensic RAID reconstruction software to analyse RAID striping algorithms and reassemble missing data.
  • Simulated the missing portions of the failed drives using advanced RAID parity reconstruction techniques.

Step 3: File System Recovery & Data Extraction

  • Extracted usable file fragments and manually reconstructed large documents and multimedia files.
  • Rebuilt the file system to restore the original folder structure as closely as possible.

Step 4: Data Integrity Verification & Secure Transfer

  • Conducted a final integrity check to ensure all recovered data was functional.
  • Successfully transferred recovered files to a new, stable storage system.

The Result

We successfully recovered over 92% of the client’s critical data, including:
Business documents and work-related files
Multimedia and creative projects
Database and configuration files

The client was able to resume operations with minimal data loss, ensuring their TerraMaster NAS failure did not impact long-term business continuity.
