⚠️ Common RAID 0 Failure Scenarios (Top 30 Errors & How We Resolve Them)

1. Accidental RAID Deletion

Issue: RAID 0 volume removed from controller or software RAID config.
Recovery: Reconstruct stripe order and size via raw disk analysis, then rebuild volume without writing to disks.

2. RAID Member Disk Failure

Issue: One or more disks unreadable or inaccessible.
Recovery: Clone remaining disks, stabilise failed disk using hardware imaging; reconstruct lost stripes via parity-free reconstruction.

3. RAID Controller Failure

Issue: Controller no longer detects RAID 0.
Recovery: Use manual disk analysis to reconstruct array outside the controller; rebuild logical volume.

4. Incorrect Disk Order

Issue: Disks connected in the wrong sequence post-move or controller reset.
Recovery: Identify correct disk order via entropy matching, header analysis, and interleave patterns.

5. Power Surge or Electrical Fault

Issue: Sudden power loss damages firmware or PCB.
Recovery: Replace controller board or transplant ROM chip; rebuild stripe array once disk images are obtained.

6. Corrupt File System (NTFS, ext4, HFS+)

Issue: Volume mounts, but file access fails.
Recovery: Mount logical volume from raw image, run file system repair, or perform direct file carving.

7. Firmware Bug in NAS Device

Issue: QNAP or Synology updates corrupt RAID config.
Recovery: Access underlying disk structure via Linux environment, reconstruct RAID outside of vendor’s OS.

8. RAID 0 Expansion Failed

Issue: User added drive to increase capacity, leading to corruption.
Recovery: Revert to pre-expansion layout, recover from historical RAID metadata, or partial recovery from individual disks.

9. Operating System Crash During Write

Issue: Critical write interrupted.
Recovery: Use journaling/metadata analysis to restore incomplete writes and recover stable version of the data.

10. Sectors Going Bad Over Time

Issue: Bit rot causes silent corruption.
Recovery: Use ECC-enabled imagers to map and bypass affected blocks.

[Additional errors up to 30 can be continued in documentation or downloadable technical reference.]

🧰 Top 20 RAID 0 Virtual Disk Failures & Our Recovery Process

1. Corrupt VHD/VMDK files inside RAID 0 – Mount via hex editor, carve internal file system.
2. RAID 0 containing Hyper-V VHDX – Extract disk image, emulate guest OS, restore guest FS.
3. Missing Partition Table in VM Host – Recreate partition entries from backup superblocks.
4. ESXi VMFS corruption across RAID 0 – Rebuild flat VMDK from constituent parts.
5. Snapshot Chain Broken – Analyse delta files and rollback base to nearest good state.
6. VDI corruption in VirtualBox – Decompress image manually and extract data layer.
7. Boot Loop in Virtual Guest OS – Use forensic boot bypass tools to mount and copy data.
8. File System Misalignment on RAID – Adjust offsets to re-align guest OS partitions.
9. Multi-VM RAID Volume Reformat – Identify lost headers, recreate container layout.
10. RAID 0 with nested BitLocker – Decrypt image after key verification; repair host/guest FS.
11. Lost Hypervisor Configuration – Reconstruct .vmx or .xml file manually.
12. RAID holding raw forensic images – Parse headers, identify volume start points.
13. RAID-backed iSCSI Target Failure – Mount LUN manually and restore file system.
14. NTFS corruption in guest – Rebuild MFT/MFTMirr from backup clusters.
15. Unresponsive RAID NAS with VMs – Extract drives from NAS, recover via standalone Linux host.
16. Parity-Free Guest Failure – Recover using signature and entropy-based carving.
17. Virtual appliance corruption – Manually rebuild OS layer to access embedded content.
18. Containerised RAID 0 environments – Mount LVM volumes inside Docker/NFS stack.
19. RAID 0 used in file archival – Recover zip/rar/7z from byte-misaligned fragments.
20. Overwritten partition table by OS reinstall – Reconstruct LBA maps manually.
