Synology DiskStation NAS devices are widely used for family storage, personal backups, and multimedia libraries. However, when a RAID 0 array is accidentally initialised, it can wipe the RAID configuration, making stored data inaccessible. Unlike other RAID levels, RAID 0 has no redundancy, meaning any loss of configuration or corruption can lead to complete data loss unless professionally recovered.
This case study details how we successfully recovered precious family photos, videos, and documents from a Synology DiskStation 2-bay NAS in a RAID 0 setup, after an accidental RAID initialisation erased the RAID configuration.
As Cambridge Data Recovery, with 25 years of experience, we used RAID metadata reconstruction, NAS file system repair, and deep sector-level data extraction techniques to restore the family’s lost data.
The Challenge: Synology DiskStation RAID 0 Array Initialized by Mistake
A family contacted us after their Synology DiskStation NAS lost all stored data, with the following issues:
- Accidental RAID initialization wiped the RAID configuration.
- The NAS no longer recognised any files, showing an empty volume.
- Attempts to recover data using Synology’s built-in recovery tools failed.
- The NAS contained years of family photos, home videos, and personal documents.
Since RAID 0 distributes data across both drives without redundancy, accidental initialization can make data difficult to retrieve without expert RAID reconstruction.
Diagnosis & Evaluation
When the Synology DiskStation 2-bay NAS (RAID 0 setup) arrived at our cleanroom facility, we conducted a full RAID and file system diagnostic. Our findings:
- RAID configuration metadata was erased, preventing normal access to stored files.
- File system damage (EXT4/Btrfs) made directory structures unreadable.
- No physical drive failures detected, meaning logical recovery was possible.
Since RAID initialization does not immediately erase all data, we prioritized manual RAID reconstruction and NAS volume recovery.
The Recovery Process
1. Cloning & Imaging Both RAID 0 Drives to Prevent Further Data Loss
To preserve recoverable data, we:
- Created forensic sector-by-sector clones of both RAID 0 disks.
- Used advanced imaging tools to extract readable sectors and bypass corrupt areas.
2. Rebuilding the RAID 0 Array & NAS File System
Since the RAID metadata was erased, we:
- Manually reconstructed the RAID 0 array based on striping patterns and disk sequence.
- Restored missing RAID headers and metadata to reassemble the volume.
3. Extracting & Verifying Family Data
Once the RAID 0 structure was successfully rebuilt, we:
- Recovered family photos, videos, and important documents.
- Checked all media files for integrity and usability.
- Transferred the fully restored data to a secure external backup.
The Results: 98% Data Recovery Success
Thanks to our RAID 0 reconstruction and NAS volume repair techniques, we successfully recovered 98% of the family’s lost data, including:
✅ Decades of family photos and videos
✅ Personal documents, PDFs, and archived emails
✅ Organized file structures restored for easy access
The family was able to regain access to their priceless memories, preventing the permanent loss of sentimental and personal data.
