⚠️ Common Synology DS423 NAS Issues We Recover
The Synology DS423 is a robust 4-bay NAS ideal for both home and business environments. However, like any multi-drive system, it is still vulnerable to:
- Multiple Drive Failures in RAID 5 or SHR configurations
- Failed RAID rebuild or rebuild interruption
- Corrupt Btrfs or EXT4 file system
- Power outages causing data corruption
- Disk recognition errors after firmware updates
- Deleted shared folders or accidental reinitialisation
- Failed DSM (DiskStation Manager) upgrade or crash
- Bad sectors and degraded RAID volume
When any of these problems occur, the data becomes inaccessible—even though it may still reside on the disks.
🛠️ Our Professional Synology NAS Data Recovery Process
Here’s how our expert team typically recovers data from a failed Synology DS423 NAS:
1. Initial Assessment & Disk Imaging
- All disks are labelled and imaged using forensic-grade hardware to prevent further degradation.
- Drives are not repaired but cloned, ensuring the original media is untouched.
2. RAID Analysis & Virtual Reconstruction
- We analyse metadata from each drive to determine the original RAID parameters (e.g., RAID 5, RAID 6, SHR).
- A virtual RAID array is constructed using the cloned images, simulating the NAS environment.
3. File System Repair (Btrfs or EXT4)
- If the file system is corrupt, we use advanced tools to repair or bypass damaged volume structures.
- For Btrfs volumes, subvolumes and snapshots are also scanned for recoverable data.
4. Data Recovery & File Extraction
- Once the virtual RAID is successfully mounted, user data, configuration files, and shared folders are extracted.
- Priority is given to preserving folder structure, timestamps, and file integrity.
5. Verification & Return
- Data is verified for completeness and integrity.
- Recovered files are returned to the client on an encrypted external drive.
