RAID & Server Data Recovery in London
When a server or storage array fails, your whole business can stop. Data Retrieval Ltd recovers data from failed RAID arrays, NAS devices, SANs and virtualised servers – from two-disk office NAS units to large enterprise arrays with 30TB drives.
We work in our London SE1 lab, remotely over a secure connection when the hardware is healthy, or at your premises when data cannot leave the building.

- RAID 0, RAID 1, RAID 4, RAID 5, RAID 6
- RAID 0+1, RAID 10, RAID 50 and RAID 60
- JBOD, spanned and concatenated volumes
- Synology Hybrid RAID (SHR and SHR-2), ZFS RAID-Z1/Z2/Z3, Btrfs RAID, Unraid, Windows Storage Spaces (simple, mirror and parity)

Before You Do Anything
If your array has failed: do not force a rebuild, re-initialise the array, run CHKDSK/fsck, or swap drives between slots. Label every disk with its slot number, shut the system down cleanly if you can, and call us on 020 7064 4996. Most unrecoverable RAID cases we see were made worse by a rebuild attempted on the wrong disk.

Frequently asked questions
How is my data kept confidential?
All work is carried out in-house by our own engineers – nothing is outsourced – and we are registered with the ICO (ZA060744), handling your data under UK GDPR.
Can you recover a server that was hit by ransomware?
Sometimes. Depending on the strain, we may be able to recover shadow copies, unencrypted file fragments, virtual machine disks or earlier snapshots. We also help you avoid paying criminals where possible. Call us before wiping or rebuilding the server.
