✅ Synology NAS with 4 x 18TB Drives – RAID5 Failure, 100% Data Recovered

Case ID: MI-0723-ST18000NM000J
Configuration:

  • NAS Brand: Synology

  • Drives Used: 4 × Seagate Exos ST18000NM000J (18TB each)

  • RAID Level: RAID 5

  • Total Usable Capacity: ~54TB

  • Data Loss Volume: Approx. 22TB

  • Drive Issue: One disk unreadable, RAID5 crashed

Customer Complaint:
Customer reported that their Synology NAS unit became unresponsive, and one of the 18TB Seagate Exos drives was no longer detected. The RAID5 array failed, making the entire data volume inaccessible. Critical business data was stored on the NAS, with no recent backup available.

Issue Diagnosis:

  • One of the 18TB disks was physically degraded and unreadable.

  • RAID metadata became corrupted, and the array could not rebuild automatically.

  • Logical volume structure was heavily fragmented.

  • Multiple filesystems identified with nested folder structures and large media/project files.

Recovery Process:

  • Performed sector-level cloning of all 3 healthy drives and partial clone from the failed drive.

  • Reconstructed the exact RAID5 parameters (block size, order, parity) manually.

  • Used specialized NAS recovery tools to simulate RAID environment.

  • Rebuilt the logical volume and mounted EXT4/BTRFS file system.

  • Verified and extracted 100% of the user data without file loss.

Outcome:
✅ 100% Data Recovery Achieved
All 22TB of lost data was successfully recovered, including shared folders, virtual machine backups, databases, and project files.

Customer Status:
✅ Data Delivered on New Backup Drive
Customer received complete data in structured folders. Business operations were fully restored without further data loss.
