How we recover DiskStation 4-bay value data
We image every member drive, identify the RAID layout and file system, and rebuild the volume offline – the NAS itself does not need to work.

Common questions
Can you recover data from a failed Synology DiskStation 4-bay value?
In most cases, yes. Arrays are reconstructed from drive images on our own systems, including SHR, Btrfs, XFS, ZFS and proprietary layouts, so your shares come back intact.
Where do I find my NAS model number?
The model name is on the front or rear label of the unit, for example DS920+ or TS-453D.
What does data recovery cost?
Every case starts with a professional evaluation (£94.80), followed by a fixed quote.
