Synology is one of the most popular NAS platforms in the world – and one of the most common in our lab. A Synology stores data on proprietary SHR (Synology Hybrid RAID) or standard RAID layouts on top of ext4 or btrfs, and the operating system (DSM) adds another layer that can fail independently of the disks.
Synology failure scenarios
- A drive fails and the SHR/RAID pool shows degraded or crashed
- DSM crashes or a failed update leaves the volume unmountable
- The “pool crashed” message appears after a power event
- Accidental factory reset, deletion, or volume removal
- Drives pulled and inserted into the wrong slots after a unit failure
Synology SHR vs. RAID recovery
SHR (Synology Hybrid RAID) is a flexible layout that combines drives of different sizes. Recovering it requires understanding Synology’s specific metadata, not just standard RAID geometry. Our engineers have deep experience with both SHR and classic RAID on Synology units.
- Don’t reinstall DSM – it can wipe the volume metadata
- Don’t click “Repair” without a full backup of every drive
- Don’t shuffle drives between slots or units
Often yes – if the data area wasn’t overwritten. The earlier you stop, the better the odds. Our free evaluation will tell you honestly.
How we recover Synology data
We image every drive, analyze the SHR/RAID layout and Synology metadata, rebuild the volume in software, and extract your files. Remote diagnostics via ARRM are available for many cases – no shipping needed.
