Lacie Big Disk Recovery – RAID 0 Failure & Not Recognised

A client contacted Brighton Data Recovery after their LaCie Big Disk (4-disk system) suddenly stopped being recognized. The reported issues included:

  • The LaCie support team in France confirmed that it was a 4-disk RAID 0 system, meaning if one disk failed, all data would become inaccessible.
  • One of the four disks had failed, preventing the RAID 0 array from functioning.
  • The client had no backup, meaning all stored data was at risk of permanent loss.
  • The LaCie Big Disk contained business-critical files, project documents, and personal archives.

Since RAID 0 provides no redundancy, a forensic-level RAID reconstruction and data recovery approach was required.

Our Expertise in LaCie Big Disk RAID 0 Recovery

With 25 years of experience, Brighton Data Recovery specialises in:
✔ Recovering data from failed RAID 0 arrays with missing or damaged disks
✔ Manual RAID reconstruction and striping reassembly
✔ Forensic-level data recovery using Acelabs PC3000, DeepSpar imaging, and advanced RAID tools

Diagnosis & Recovery Process

Upon receiving the LaCie Big Disk and its four drives, our engineers conducted a detailed forensic analysis. The key findings included:

  • One drive had suffered a mechanical failure, causing the RAID 0 volume to become unreadable.
  • The remaining three drives were intact, meaning a partial RAID 0 reconstruction was possible.
  • Since RAID 0 distributes data across all disks without redundancy, the missing data from the failed drive had to be reconstructed.

To successfully recover the client’s lost files, we implemented a multi-step RAID 0 recovery strategy:

Step 1: Disk Imaging & Data Preservation

  • Created sector-by-sector forensic clones of the three remaining healthy drives using DeepSpar Disk Imager.
  • Opened the failed hard drive in an ISO-certified cleanroom, where we:
    • Replaced damaged read/write heads to extract as much data as possible.
    • Created a partial clone of the failed disk to reconstruct missing RAID data.

Step 2: RAID 0 Reconstruction & Stripe Analysis

  • Analysed RAID 0 striping patterns and block sizes to manually rebuild the missing portions of the failed disk.
  • Used advanced RAID recovery software to virtually reconstruct the RAID array and restore the original file system.

Step 3: File System Recovery & Data Extraction

  • Rebuilt the file system structure and identified recoverable files.
  • Extracted and validated documents, multimedia files, and business records.

Step 4: Data Integrity Check & Secure Transfer

  • Conducted final validation checks to confirm all recovered files were accessible.
  • Successfully transferred the restored data to a new high-capacity external storage device.

The Result

We successfully recovered 92.5% of the client’s lost files, including:
✅ Business documents, spreadsheets, and project files
✅ Multimedia files, high-resolution images, and videos
✅ Personal and archived data from past projects

The client was able to restore all critical data, avoiding catastrophic data loss despite the RAID 0 failure.
