⚠️ Top 30 RAID Errors We Recover From
We recover data from a wide range of RAID failures. Below are common RAID issues with simplified technical recovery insights:
- Multiple Drive Failures – Sector cloning, RAID map reconstruction, parity rebuilds.
- RAID Controller Failure – Bypass controller, recreate RAID manually using sector-level mapping.
- RAID Rebuild Failure – Prevented by faulty disk; manual rebuild from cloned images using parity data.
- Incorrect Disk Order – Disk sequence identified using hex comparison and stripe pattern analysis.
- Accidental Reinitialisation – Recovery via metadata detection and RAW volume scanning.
- Bad Sectors on Disks – Drives cloned with recovery imaging software, followed by array rebuild.
- Parity Drive Failure – Rebuild using remaining parity or mirror copies depending on RAID level.
- RAID Degradation Over Time – RAID state simulated for partial readout and recovery from healthy blocks.
- RAID Array Not Mounting – Logical rebuild of volume structures and partitions.
- Deleted RAID Partition – Signature-based recovery and RAID configuration reconstruction.
- RAID Metadata Corruption – Low-level RAID header reconstruction and file system rebuild.
- Failed Hot-Swap Drive – Hot-swap damage reversed with manual synchronisation.
- Drive Not Detected – Interface repaired or NAND-level access enabled for SSDs.
- Foreign Configuration Detected – Forced configuration rollback using controller or software RAID tools.
- Disk Sector Misalignment – Stripe analysis realigns data across members.
- Unrecognised File System – Recovered using file carving and volume metadata analysis.
- Stuck in Rebuild Mode – Abort rebuild safely and extract data before damage escalates.
- Corrupt Virtual RAID Volume – VHD/VHDX/VMFS/VDI reconstruction from RAW data.
- OS-Level RAID Driver Issues – Bypassed by imaging and external RAID emulation.
- Deleted Files in RAID – File system scan for deleted file records and signature recovery.
- Mixed Disk Sizes or Types – Virtual volume corrected via block size matching.
- Firmware Conflict Across Drives – Unified firmware or independent sector analysis to bypass mismatch.
- Dropped NAS or Server – Mechanical repairs performed before data imaging.
- Power Surge Damage – PCB or controller repair followed by RAID rebuild.
- Volume Appears as RAW – Volume table reconstruction and data recovery.
- File Corruption from Rebuild Error – File-level reconstruction with comparison across data sets.
- RAID Set Not Initialised – Manual recovery of array layout and stripe order.
- RAID Deletion During Setup – Previous RAID metadata retrieved from unallocated disk space.
- Corrupt LVM or BTRFS RAID (Linux) – Mount issues resolved through manual volume extraction.
- BitLocker Encrypted RAID Volume Failure – Recovery with key or TPM data; clone before decryption attempt.
🧱 Top 20 RAID 5 Virtual System Problems & How We Recover
- VHD/VHDX File Corruption – File signature repair and virtual disk mount.
- Virtual RAID Volume Not Booting – Virtual controller bypass and direct disk mapping.
- Missing VMDK or VHD – File signature carving and RAID-based VM file reassembly.
- Corrupt Virtual RAID Metadata – Manual creation of virtual array structure.
- Inaccessible VMFS Volume – Raw data access and flat file extraction.
- RAID Storage Pool Degraded – Pool deconstructed and virtual RAID mounted from individual disks.
- Hyper-V Snapshot Corruption – Merged virtual files reconstructed from parent disks.
- Virtual Disk Appears as RAW – Low-level access used to mount image and extract files.
- Deleted Virtual Machine Files – File carving and VM metadata recovery.
- Corrupt Parity Data in Virtual RAID – Error-corrected rebuild through parity regeneration tools.
- Drive Letter Missing in Host OS – Disk mounted virtually using sector analysis.
- Split VHD Files Not Opening – Re-linked through size matching and footer/header repair.
- RAID Virtual Disk Slow or Freezing – Imaged and mounted externally to prevent further corruption.
- RAID Volume Offline in Storage Manager – Reinitialised using manual header repair.
- Hypervisor Drive Mapping Corrupt – Remapped via LBA-to-file structure.
- ESXi RAID Failure – Datastore manually rebuilt via VMFS volume analysis.
- Failed Veeam Backup Repository on RAID – Corrupt backup metadata recovered from RAID clone.
- NAS iSCSI Target Corruption – LUN extracted manually from RAID backend.
- VM Image File Fragmented Across Disks – Reassembled using stripe pattern mapping.
- Clustered RAID Virtual Disk Error – Manual node recovery and shared volume extraction.
