🔧 Virtualised RAID 5 Failures – Top 20 Problems

Many RAID 5 systems operate under virtual machines (VHDX, VMDK, QCOW2), and we frequently recover:

  1. Corrupt virtual disk headers
  2. Snapshot chain corruption
  3. Orphaned or dismounted VM disks
  4. Failed RAID under Hypervisor (VMware, Hyper-V, Proxmox)
  5. Corrupted VMFS/NTFS volumes
  6. Partially overwritten VHDX files
  7. Failed live migrations
  8. VM datastore inaccessible after RAID degradation
  9. Power cut during VM disk expansion
  10. vSAN corruption
  11. Guest file system corruption within VM
  12. VM drive file deleted or moved
  13. Faulty disk cache sync in VM host
  14. Thin-provisioned disk corruption
  15. RAID rebuild broke guest disk consistency
  16. Snapshot rollback failure
  17. Broken LVM inside Linux guest
  18. Encrypted VM disk inaccessible after host failure
  19. RAID rebuild completed but guest files missing
  20. Recreated VM folder structure but files unreadable

Recovery Process:

  • Clone all RAID disks
  • Virtually rebuild the array using forensic RAID tools
  • Mount and extract VMs from recovered RAID volumes
  • Deep repair or carving of VM contents (VHDX, VMDK, etc.)
  • Recover guest files (Windows or Linux)

Micky Mellon, Adamsdown, Cardiff

My SD card corrupted and all of my pictures were lost from a photoshoot I had done. I looked for photo recovery experts and found Cardiff Data Recovery, and all I had to do was pop it in the post for them to fix. In under a week I had all my files back which was just outstanding service.

Tony and the Cardiff Data Recovery team did an excellent job of recovering file data that others considered lost and unrecoverable. Luckily I clearly found the most capable Data Recovery Service as in just a few days I got a USB Storage device with all my deleted files.

Ben Thornhill, Caerphilly, UK

There were years worth of my irreplaceable Pictures and Videos on my Windows computer which had a boot error. I tried some recovery discs but had no luck. Cardiff Data Recovery salvaged my files within 48 hours and backed up onto a USB stick for me. Thanks for recovering my data, a truly remarkable service.

Jane Heath, Merthyr Tydfill, UK

I switched on my Dell laptop to see a message that all of my files were encrypted and I had to pay to get them back. Rather than give in to these horrible people I contacted Cardiff Data Recovery. They took control and said they could remove the ransomware and get all of my files back for me. Not only did they fully recovered my data files on my laptop, but they also cleaned all the viruses and malware off, and installed some reputable anti-virus for me to complete the perfect service. I know who I’d give my money to again in this circumstance.
