RAID 5 Data Recovery

With over 25 years of hands-on experience, Coventry Data Recovery is the go-to solution for critical RAID 5 file recovery. Whether you’re a home user with a NAS device or an enterprise managing multi-disk rack-mounted RAID arrays, our engineering team recovers data from the most complex RAID 5 failures – including controller-level faults, drive degradation, accidental configuration changes, and virtual system corruption.

Services Offered – Professional RAID 5 Data Recovery

We recover data from all types of RAID 5 configurations, including:

• Software-based RAID 5 (Windows Storage Spaces, mdadm)
• Hardware-based RAID arrays (with RAID controllers from Dell, HP, Adaptec, Areca, etc.)
• NAS units with embedded Linux or proprietary OS (e.g., Synology DSM, QNAP QTS)
• Virtualised environments (VMware ESXi, Microsoft Hyper-V, Citrix XenServer)
• Rack-mounted RAID 5 servers (enterprise, government, education, CCTV)

We support RAID 5 arrays from 2 to 32 disks, across all interfaces: SATA, SAS, SCSI, NVMe, and hybrid systems.

Common RAID 5 Hard Drive Faults We Recover From

Here are the top 30 RAID 5 file recovery faults, each with a brief technical explanation and our recovery methodology:

1. Multiple Drive Failure
   Fault: Two or more disks offline simultaneously.
   Recovery: Binary cloning of working drives, sector-level parity analysis, synthetic RAID reconstruction.
2. Rebuild Failure
   Fault: Errors during RAID rebuild resulting in corrupted parity.
   Recovery: Rollback to pre-rebuild disk image, manual parity reconstruction using XOR math.
3. RAID Controller Failure
   Fault: RAID card corruption or firmware malfunction.
   Recovery: Controller-independent RAID reconstruction using drive metadata and sector sequencing.
4. Array Metadata Corruption
   Fault: Damaged RAID header preventing mount or rebuild.
   Recovery: Raw disk parsing to extract RAID geometry, block size, stripe pattern, and order.
5. Accidental RAID Reinitialisation
   Fault: RAID deleted and reinitialised without backup.
   Recovery: Sector-level recovery from unallocated space, reverse engineering of array topology.
6. Incorrect Disk Reordering
   Fault: Drives inserted in wrong order during troubleshooting.
   Recovery: Stripe pattern analysis and disk order permutation with checksum verification.
7. Parity Sync Error
   Fault: Bad parity across stripes due to interrupted writes.
   Recovery: Recalculate correct parity per stripe using known valid blocks.
8. Firmware Update Failure
   Fault: Failed RAID controller update bricks volume.
   Recovery: Reconstruct RAID using cloned drives and third-party controller emulators.
9. Bit Rot / Silent Corruption
   Fault: Gradual degradation of sectors without SMART alerts.
   Recovery: Pattern detection, ECC analysis, parity validation.
10. Power Surge Damage
    Fault: Drives won’t spin up, PCB damage.
    Recovery: PCB swap and firmware transplant from donor drives.

Top 20 Virtualised RAID 5 Failures and Solutions

1. Corrupt VHD/VMDK on RAID 5
   Recovery: Extract VHD/VMDK from logical RAID clone, repair header and mount manually.
2. Virtual Disk Descriptor Corruption
   Recovery: Hex-level repair of .vmdk or .avhdx descriptor files and chain re-linking.
3. Hyper-V Host Failure with Missing VM Files
   Recovery: RAID emulation, data carving from unstructured volumes.
4. VMFS File System Corruption (VMware)
   Recovery: VMFS metadata scan and file recovery with custom parsers.
