HP ProLiant RAID 5 Hard Drive Data Recovery – Inaccessible Data Due to Degraded Drives

A corporate client from Newcastle Upon Tyne contacted Newcastle Data Recovery after their HP ProLiant RAID 5 server became inaccessible. The reported issues included:

• The RAID controller could not read critical parts of the array, causing system failure.
• Multiple drives showed degradation, leading to potential data corruption.
• HP Server Support diagnosed degraded drives but could not assist in data recovery.
• The server contained business-critical data, including financial records, client databases, and operational files.

Since RAID 5 arrays rely on parity for data redundancy, and degraded drives can lead to corrupt RAID metadata, a forensic-level RAID reconstruction was required.

Our Expertise in HP ProLiant RAID Recovery

With 25 years of experience, Newcastle Data Recovery specialises in:
✔ Recovering data from degraded or corrupted RAID 5 arrays
✔ Handling RAID controller failures and parity reconstruction
✔ Using advanced RAID recovery tools like Acelabs PC3000 RAID, UFS Explorer, and R-Studio

Diagnosis & Recovery Process

Upon receiving the 8-drive HP ProLiant RAID array, our engineers conducted a detailed forensic RAID assessment. The key findings included:

• Two drives had extensive bad sectors, leading to RAID controller failure.
• RAID metadata was partially corrupted, preventing the system from identifying the correct array configuration.
• The parity stripe was intact, meaning data could be reconstructed.

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

Step 1: Secure Drive Imaging & Parity Reconstruction

• Used Deepspar Disk Imager to create sector-by-sector images of all RAID drives.
• Applied Acelabs PC3000 RAID tool to reconstruct the RAID parity data.

Step 2: RAID Virtualization & File System Repair

• Used UFS Explorer RAID Recovery to rebuild the degraded RAID 5 array in a virtual environment.
• Repaired file system inconsistencies and RAID metadata corruption.

Step 3: Data Verification & Secure Transfer

• Verified all recovered files for integrity using checksum validation.
• Transferred all restored data to a secure external RAID system for easy access.

The Result

We successfully recovered 99.2% of the client’s business data, including:
✅ Financial records, client databases, and confidential reports
✅ Operational files, business contracts, and employee records
✅ Fully intact RAID 5 array reconstruction for future redundancy

The client was able to restore their HP ProLiant server without permanent data loss.
