NAS Data Recovery Sheffield

Your NAS quietly stored everything the family or business needed — until a drive failed, a rebuild went wrong or the box itself died. We recover Synology, QNAP, WD My Cloud, Buffalo and Netgear NAS systems for Sheffield homes and businesses.

Free diagnostic on every nas external drive job. Fixed quote before any work — and no fix, no fee.

// top 10 faults we recover from

The ten ways they fail

Every nas external drive job starts by matching the symptoms to the fault — these ten cover almost everything that reaches the bench.

Single drive failure in RAID

Survivable by design — but the array is now one failure from disaster and rebuilds are the risky part.

Second failure during rebuild

The most common NAS catastrophe we see: the rebuild stresses the survivors and one gives up.

Volume crashed / degraded

The logical structure broke — data intact, index gone, dashboard full of red.

Accidental re-initialisation

The setup wizard 'helpfully' wipes the config — and sometimes starts on the data.

Failed firmware update

The box bricks mid-update with the array stranded inside perfectly healthy drives.

Power-cut corruption

Interrupted parity writes desync the members; the array refuses to mount afterwards.

Dead enclosure (PSU / board)

The NAS dies, the drives don't — the array is rebuilt virtually from the member disks.

Deleted shares or snapshots

Files and snapshots removed from the pool are carvable while the space survives.

Ransomware on the NAS

Exposed NAS boxes get encrypted like PCs — snapshots and remnants often survive underneath.

Drive-order confusion

Drives pulled without labels then reinserted wrong — solvable, but stop before 'trying combinations'.

RAID doesn't mean backed up

A NAS spreads data across drives in RAID or proprietary layouts (Synology SHR, Drobo BeyondRAID). One failed drive is survivable; a second failure during the rebuild is the disaster we see most. We image every drive first, then reconstruct the array virtually — parameters, order and offsets worked out from the data itself — before extracting your files. Nothing is written to your original drives at any stage.

Send the drives, labelled

Power the NAS down and don't run a rebuild or re-initialise, however tempting the wizard makes it look. Remove the drives and label their bay order (1, 2, 3…) with a marker or sticky notes, then send the drives — the enclosure itself can stay with you. For a single-drive unit like a My Cloud, open the enclosure and send just the drive too; if it's sealed and won't open easily, call us first on 0800 689 0668.

// the equipment we use

A professional lab, not software guesswork

NAS recovery is RAID recovery plus vendor-specific logic, and the bench covers both:

Parallel imaging bays

Every member drive is imaged simultaneously on dedicated hardware before any analysis — originals never join a rebuild again.

PC-3000 RAID / Data Extractor

Works on the drive images to solve array geometry — member order, block size, rotation, offsets — and mount the virtual array.

PC-3000 UDMA + clean bench

Failed member drives get the full hard drive treatment (heads, firmware, PCB) so they can be imaged like the rest.

Virtual RAID reconstruction software

Entropy and parity analysis to verify the solved geometry, then file-system extraction from the reassembled volume.

Vendor layout parsers

Synology SHR, Drobo BeyondRAID, QNAP flex volumes, mdadm/LVM and BTRFS/ext4 — the proprietary layers translated back to files.

Single-bay enclosure kit

My Cloud-style single-drive units open cleanly; their Linux-formatted drives read natively on the bench.

NAS units on the bench most weeks

Two-bay home boxes to rack-mounted small-business arrays — label the drive order before anything leaves the building.

// before you post it

Sending it in — remove the drive if you can

Power the NAS down, remove the drives, and LABEL each one with its bay number (1, 2, 3…) before you send them — the order is critical to rebuilding the array. Send the drives rather than the whole enclosure, unless it's a single-bay unit.

// getting your device to us

Post or courier your device — it's simple

Most customers post or courier their device to us — it arrives next morning, and the free diagnostic starts the day it lands.

Sending a drive from a computer, laptop, MacBook, iMac or server? Please remove the internal hard drive or SSD and send us just the drive — we don't provide an internal drive-removal service. If the storage is soldered in (e.g. Apple Silicon), call us first on 0800 689 0668.

  • Wrap the device in bubble wrap or a padded envelope — no need to include cables or power supplies.
  • Print and enclose the booking-in & shipping form (PDF) with your name, phone number and a brief description of what happened.
  • Send by Royal Mail Special Delivery or any tracked courier for full insurance in transit.
  • Prefer to hand it over in person? You can drop it in at reception at the address shown, Mon–Fri 9:00am–5:30pm.

// nas external drive recovery questions

Common questions

Rarely. 'Crashed' usually means the array's logical structure has broken, not that the data is destroyed. We image each drive and rebuild the volume in software to get your files back.
Often, yes. The second 'failed' drive is frequently readable with lab imaging hardware even when the NAS rejects it. Between a full image of it and the healthy drives, the array can usually be reconstructed.
No — a rebuild onto a failing drive is the most common way recoverable data becomes unrecoverable. Power down, label the drives, and let us image everything first.
Yes. A single-drive NAS is essentially a network wrapper around one hard drive, usually with a Linux file system your PC can't read. Open the enclosure, remove the drive and send us just the drive — we don't remove drives from devices. If the case is sealed and won't open, call us first on 0800 689 0668.
