A D-Link ShareCenter dropped off the network and stopped serving files after the disk inside it failed mechanically. Recovering a NAS means treating it as two problems at once: a physically sick drive, and the Linux storage layout a NAS writes on top. We handled both and returned the shared data.
The ShareCenter had been the shared drive for a small office, holding documents and the backups everyone assumed were safe on it. One day it vanished from the network and its status light showed a fault. The disk inside had failed mechanically — it was no longer spinning up properly — which is why the NAS could no longer read it. With the only copy of the shared data on that disk, the unit was powered off and sent in before any further damage could occur.
A NAS is a small Linux computer wrapped around one or more disks. That means a failed NAS combines a hardware problem — here, a mechanically failed drive — with a software one: the data is stored using Linux file systems and volume managers (ext4, XFS, LVM, often layered over software RAID) that a Windows or Mac computer can't read at all. Recovering it requires fixing the drive first, then understanding and reassembling the NAS's own storage layout by hand.
The disk was opened in controlled clean-air conditions to diagnose the mechanical fault, and the failed components — the read-write head assembly — were replaced with matched donor parts so the drive could be spun up under control. It was then imaged with an adaptive strategy that secured the healthy areas first and worked patiently over the weaker zones, pulling back the maximum readable data without over-stressing the repaired drive. All recovery then continued from the image, not the fragile original.
From the image, the NAS's Linux storage stack was reassembled: the volume-manager and file-system structures were parsed, the correct parameters identified, and the ext-family file system mounted read-only so the shared folder tree could be walked. Where the file system's own structures had been affected by the drive's bad areas, they were repaired against the journal and redundant copies, so the folders and file names came back as the office had known them rather than as anonymous fragments.
Documents and backup files were opened across the recovered tree to confirm they were intact, then the data was returned on a fresh drive. Around 98% came back, the small remainder matching sectors lost to the mechanical damage. We also made the point that a NAS — especially a single-disk one — is storage, not a backup: the shared files it held needed a second copy somewhere else, and now have one.

Send it to us for a free, no-obligation diagnostic. We’ll tell you what can be recovered and put a fixed price in writing before any work starts — and on most jobs, if we can’t get your data back, there’s nothing to pay. Post your device in, or drop it to us by appointment.
Yes — single-drive or multi-drive, any make. We recover the disks (repairing them physically if needed), then reassemble the NAS's Linux storage layout to rebuild the shared folders. Send the whole unit or just the drives, labelled with their bay order.
A NAS holds data reliably day to day, but on its own it isn't a backup: one failure can take everything with it. Once your data is recovered, keeping a second copy elsewhere — another device or the cloud — is what protects it.
NAS and multi-disk recoveries start from £500 plus VAT, with a fixed written quote after a free diagnostic and no fix, no fee on most jobs. Physical repairs carry a deposit toward parts and bench time.
