At Exeter Data Recovery, we specialise in G-RAID data recovery, including complex multi-disk systems like the G-RAID Shuttle with 8 x 18TB drives configured in RAID 5. If your system has suffered a drive failure, a failed rebuild, or is now completely inaccessible, our team of RAID recovery engineers can recover your critical data using proven, non-destructive techniques.
With over 25 years of RAID recovery expertise, we offer the technical precision required to safely reconstruct high-capacity storage arrays where other services fall short.
Understanding the G-RAID Shuttle System & RAID 5 Vulnerabilities
The G-RAID Shuttle 8 is a professional-grade storage unit commonly used in video editing, media archiving, and large-scale data workflows. When configured in RAID 5, the system offers redundancy for a single drive failure using distributed parity.
However, if a replacement drive is introduced and the RAID rebuild fails or is interrupted, the array may enter a degraded or inaccessible state—leading to the scenario where no data is available, and the rebuild process stalls.
Step-by-Step Technical Recovery Process for G-RAID Data Loss
Our G-RAID data recovery process involves a thorough and methodical approach that safely reconstructs the array without risking additional data loss.
1. Device Intake & Assessment
- Each of the 8 hard drives (18TB) is carefully catalogued and labelled upon arrival
- Drives are write-protected to prevent any modification during diagnosis
- We assess drive health, identify the failed or replaced drive, and review SMART logs
- A physical inspection is performed for signs of damage, mislabelling, or rebuild errors
2. Disk Imaging – Clone All Drives
No rebuild is attempted during this phase. Instead, we:
- Perform a bit-level clone of all drives using professional imaging equipment (e.g. DeepSpar, Atola Insight)
- Bad sectors are handled using adaptive read strategies, with multiple passes to maximise data acquisition
- Even healthy drives are cloned to preserve evidence of the original RAID structure and parity layout
3. RAID Parameter Identification
Once clones are complete, we identify the RAID configuration details:
- Block size / Stripe size
- Parity rotation pattern (e.g. Left-symmetric, Right-asynchronous)
- Drive order and logical disk mapping
- RAID metadata and controller-specific parity structure (where available)
This step involves manual analysis and automated RAID reconstruction tools to detect the correct RAID 5 structure without relying on the RAID controller, which may have overwritten or corrupted metadata during the failed rebuild.
4. Virtual RAID Reconstruction
- A virtual RAID array is built using the cloned images
- We exclude the suspect or replaced drive from the initial parity validation
- The array is tested for logical file system consistency (e.g., exFAT, NTFS, HFS+, APFS depending on setup)
- Filesystem mounts are simulated to verify directory structures and data integrity
5. File System Repair & Logical Recovery
- If the file system is damaged due to the rebuild failure, we reconstruct it using forensic data recovery tools
- Volume headers, partition maps, and directory indexes are rebuilt from known-good sectors
- Data is extracted from the virtual array to a separate recovery volume
- Complex file types (e.g., Final Cut Pro, Adobe Premiere, raw video files) are checked for internal consistency
6. Data Verification & Extraction
- Recovered data is manually verified for file integrity and completeness
- Critical file types and user-specified directories are prioritised for early delivery
- Data is copied to a secure external drive or storage medium, encrypted if required
Supported Systems & File Systems
We support G-RAID recovery from systems using:
- G-RAID Shuttle 4, 8, and Studio XL series
- RAID 5, RAID 0, and RAID 10 configurations
- USB-C, Thunderbolt 3, and eSATA interfaces
- File systems: HFS+, APFS, NTFS, exFAT, EXT4, XFS
Common G-RAID Failures We Recover From
- Single or multiple drive failure
- Failed or incomplete RAID 5 rebuild
- Parity mismatch or corruption
- Accidental reinitialisation
- Power loss during RAID rebuild
- Controller failure or firmware bug
- RAID misconfiguration after disk replacement
- Data loss after formatting or OS update
- Files not appearing despite healthy disks

What to Do If Your G-RAID Rebuild Has Failed
- Stop using the array immediately – continued use may overwrite recoverable data
- Do not attempt another rebuild or initialise the array
- Keep all original drives, including the failed one – this may still hold essential parity data
