Asustor Lockerstor NAS Data Recovery After Drive Failure

A business using an Asustor Lockerstor NAS to manage its work network storage experienced a critical failure where the NAS would not boot up or connect to the network. Upon closer inspection, the client noticed that:

  • Two of the hard drives were unresponsive, causing the RAID array to become inaccessible.
  • Clicking noises were coming from the NAS system, suggesting mechanical drive failure.
  • All critical business data stored on the NAS was at risk of permanent loss.

With no recent backup available, the company faced the possibility of losing essential work files, which would have impacted daily operations.

With 25 years of experience, our team specialises in:
✔ Recovering RAID arrays from failed NAS systems
✔ Repairing mechanical drive failures with cleanroom technology
✔ Using forensic data recovery techniques to extract lost files

Diagnosis & Recovery Process

Upon receiving the Asustor Lockerstor NAS, our engineers conducted an in-depth forensic analysis. The key findings included:

  • Two Hard Drives Had Mechanical Failures – The clicking noises indicated read/write head damage inside the drives.
  • RAID Configuration Was Corrupt – The NAS could not rebuild the RAID array due to multiple disk failures.
  • NAS Controller Was Functional – This suggested that the data loss was caused by disk-level failures rather than a system-wide issue.

To successfully recover the company’s critical business data, we implemented a multi-step forensic NAS recovery strategy:

Step 1: Mechanical Drive Repair in a Cleanroom

  • Opened the faulty drives in a cleanroom environment to prevent contamination.
  • Replaced damaged read/write heads and temporarily restored drive functionality.
  • Successfully imaged as much data as possible from the damaged drives.

Step 2: RAID Reconstruction & Parity Repair

  • Analysed the RAID configuration used in the Asustor Lockerstor NAS.
  • Used advanced RAID reconstruction tools to virtually rebuild the array.
  • Reassembled missing parity and striping data to restore file access.

Step 3: File System Recovery & Data Extraction

  • Performed a deep forensic scan to locate fragmented or damaged files.
  • Restored the business documents, project files, and critical system data.

Step 4: Data Integrity Verification & Secure Transfer

  • Conducted a full validation check to confirm all recovered files were functional.
  • Successfully transferred all recovered data to a new NAS system for the client.

The Result

We successfully recovered over 98.5% of the business’s critical data, including:
✅ Work network documents and operational files
✅ Database and shared work folders
✅ Archived project files and essential software configurations

The company was able to restore its network storage and resume business operations within 48 hours, minimizing downtime.
