RAID 5 Data Recovery – Failed Dell PowerEdge 2600 Hard Drive Array

A client contacted Brighton Data Recovery after experiencing a RAID 5 failure on their Dell PowerEdge 2600 server, which was used to store data from multiple computers. The reported issues included:

  • Three hard drives in RAID 5 were no longer detected, making all stored data inaccessible.
  • An external and bootable hard drive was attached, which caused a RAID failure.
  • The server showed an error message and did not recognise the RAID 5 array in Device Manager.
  • The BIOS failed to detect the RAID disks, and the system showed the array as empty.
  • The client had no backup, meaning all stored data was at risk of permanent loss.
  • The RAID 5 array contained personal, work, and critical data files that needed to be recovered.

Since RAID 5 failure due to unexpected system configuration changes can corrupt RAID metadata and RAID parity, a forensic-level RAID reconstruction approach was required.

Our Expertise in RAID 5 Data Recovery

With 25 years of experience, Brighton Data Recovery specializes in:
✔ Recovering lost RAID 5 arrays after failed rebuilds or controller errors
✔ Manually reconstructing RAID metadata and striping configurations
✔ Forensic-level data extraction using Acelabs PC3000, DeepSpar imaging, and RAID-specific tools

Diagnosis & Recovery Process

Upon receiving the Dell PowerEdge 2600 and its three RAID 5 hard drives, our engineers conducted a detailed forensic evaluation. The key findings included:

  • RAID metadata corruption prevented the system from detecting the array, despite the physical drives being intact.
  • The external bootable hard drive had caused a configuration mismatch, breaking the RAID controller’s ability to recognise the existing RAID 5 setup.
  • No mechanical failures were detected, meaning the data was still present but logically inaccessible.

To successfully recover the client’s lost files, we implemented a multi-step RAID 5 recovery strategy:

Step 1: Disk Imaging & Data Preservation

  • Created sector-by-sector forensic clones of all RAID member disks to prevent further corruption.
  • Prevented additional writes to preserve the RAID striping structure.

Step 2: RAID Metadata Repair & Array Reconstruction

  • Used Acelabs PC3000 and DeepSpar tools to analyze RAID metadata and rebuild the RAID 5 configuration.
  • Virtually reconstructed the RAID array outside of the Dell PowerEdge 2600 system, restoring RAID striping and parity data.

Step 3: File System Recovery & Data Extraction

  • Repaired file system corruption (NTFS/EXT4) and recovered missing partition structures.
  • Extracted and validated personal documents, work files, and archived data.

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 secure external RAID system.

The Result

We successfully recovered 99.1% of the client’s lost files, including:
✅ Personal documents, spreadsheets, and PDFs
✅ Multimedia files, high-resolution images, and videos
✅ Archived emails, project data, and software backups

The client was able to fully restore their RAID 5 system, ensuring no permanent data loss despite the configuration failure.
