A self-employed plumber contacted us after losing access to all financial records stored on his TerraMaster NAS, with the following issues:
- All shared folders and volumes disappeared after accidental deletion or system error.
- The NAS was no longer accessible via the network.
- Attempts to restore data using TerraMaster’s built-in recovery tools failed.
- The RAID 0 setup meant there was no redundancy, increasing the risk of total data loss.
- The NAS contained all accounting files, tax records, and invoices.
Since RAID 0 provides no fault tolerance, any data loss or deletion immediately puts all files at risk, making immediate professional recovery essential.
Diagnosis & Evaluation
When the TerraMaster F4-424 Pro NAS (RAID 0 setup) arrived at our cleanroom facility, we conducted a full RAID and file system diagnostic. Our findings:
- NAS configuration metadata was lost – Preventing the system from recognizing existing shares.
- RAID 0 parity data was missing – Meaning a full RAID reconstruction was required.
- File system corruption detected (EXT4/Btrfs) – Making stored business data unreadable.
Since NAS shares and volumes were deleted, but data blocks were still present, we prioritized RAID reconstruction and raw data extraction.
The Recovery Process
1. Cloning & Imaging All RAID 0 Drives to Prevent Further Data Loss
To preserve the integrity of the existing data, we:
- Created forensic sector-by-sector clones of all RAID 0 disks.
- Used advanced imaging tools to bypass any corrupted sectors and extract readable data.
2. Manually Rebuilding the RAID 0 Array & NAS File System
Since the RAID 0 configuration was lost, we:
- Determined the exact RAID stripe size, order, and disk sequence.
- Reconstructed the RAID 0 array using forensic NAS recovery software.
3. Extracting & Verifying Accounting & Business Data
Once the RAID 0 volume was restored, we:
- Recovered accounting software data, including invoices and tax records.
- Repaired fragmented spreadsheets and financial reports.
- Transferred the fully restored business data to a secure external drive.
