Crashed volume, a NAS that won't boot, a failed rebuild or shares deleted by mistake? We recover Synology, QNAP and every other make — SHR, Btrfs and ext4. We image every disk and rebuild the volume off the box, so a dead NAS never means lost data.

If your NAS shows a crashed or degraded volume, has lost a disk, or won't boot, stop — don't let it repair, rebuild or re-sync the volume. A rebuild writes to the disks and can overwrite the very data we need, and a NAS disk put into a Windows PC will be offered up to format. Power the unit down, note which disk came from which bay, and call us. The first attempt at recovery is always the safest.
From a crashed volume to a NAS that won't boot, these are the NAS failures we recover from most — volume, hardware, rebuild and logical.
We recover every NAS — Synology, QNAP, WD, NETGEAR, Buffalo and the rest — every RAID level, SHR, Btrfs and ext4, from a two-bay box to a rack of bays. The make decides the method, not whether we can help.
Synology (DSM, SHR, Btrfs), QNAP (QTS), WD My Cloud, NETGEAR ReadyNAS, Buffalo TeraStation, Asustor, TerraMaster and Drobo · RAID 0, 1, 5, 6, 10 and SHR · ext4 and Btrfs · 2-bay, 4-bay, 8-bay and rack units, plus expansion bays.
NAS recovery means reading your data off the disks, not the box. A NAS stores everything on a Linux RAID volume — not a format Windows can read — so we image every disk, reassemble the array and file system, and recover your shares independently of the NAS itself.
Tell us the NAS — make, number of bays, RAID type, what happened. We assess it and send a written quote, usually within 48 hours. Note which disk came from which bay if you can.
We take a read-only image of every disk in the NAS on specialist hardware, including failing ones, so all the work happens on copies and your originals are never touched.
Where a disk has failed mechanically or electronically, we repair it — swapping heads, rebuilding the board — enough to image it. Drive-level repairs need 50% of the fee upfront.
We reassemble the RAID or SHR array, the LVM layer and the ext4 or Btrfs file system from the images — exactly as the NAS had it, off the box.
We extract your shared folders, files, photos, backups, virtual machines and snapshots from the rebuilt volume — pulling the most consistent copy of the data.
We check the recovered shares and files actually open and are complete before anything is returned to you.
We return your data on a new drive or NAS sized for the volume, ready to put back into service.
We recover every NAS — Synology, QNAP, WD, NETGEAR and the rest — imaging every disk and rebuilding the RAID or SHR volume off the box, so a dead NAS never means lost shares.
Tell us what happened and we will get back to you, usually within one working day.
We will be in touch shortly. For anything urgent, call 0117 332 1137.
Clear, tiered pricing for NAS recovery — with a free diagnostic and a written quote before any work starts.
A snapshot of recent NAS recoveries across crashed volumes, dead boxes, failed rebuilds and reconfiguration. Names redacted, results verified.
A disk had failed and the Btrfs volume corrupted. We imaged all four, reassembled the SHR array and recovered every share.
The NAS hardware was dead but the disks were intact. We rebuilt the RAID 5 volume off the box and recovered the lot.
Neither disk was fully dead. We repaired and imaged each, then rebuilt the mirror to recover the family photos.
The rebuild had partly overwritten the volume. We imaged every disk and reconstructed the original layout to recover it.
The box had failed but the disk was healthy. We read the Linux volume off it and recovered everything.
Little new had been written. We reconstructed the original SHR volume and recovered the shares and backups.
Reviews from real Bristol and South West clients whose NAS units we recovered.
Our Synology came up with “Volume crashed” and we lost access to the whole business overnight. They rebuilt it and recovered every share. I cannot recommend them enough.
Our NAS just died with years of family photos on it and no other copy. They got every one of them back. Worth every penny and lovely people to deal with.
A rebuild on our QNAP went wrong and corrupted the volume with all our work on it. They reconstructed it and got everything back. Fast, fair and completely honest.
Our WD My Cloud died and two other places said the photos were gone. These read the disk and recovered the lot. Genuine experts.
Gave us a clear fixed quote up front, no fix no fee, and kept us updated throughout. Recovered our two-bay Synology after both disks failed. Brilliant service.
I deleted our QNAP volume by mistake and thought we’d lost everything. They reconstructed it and recovered all our shares. Honest, skilled and reassuring.
Send us your device for a free diagnostic, and tell us a little about what happened — an engineer will review it and confirm your exact quote in writing before any work begins.
Recovering your data starts with getting the device to us. Pack it safely, add your contact details, and send it over — after we run a free diagnostic, we’ll confirm your exact price in writing before any work begins.
Posting it in? We recommend a tracked, insured service. Prefer to drop it off? You’re welcome Monday–Friday, 9am–5:30pm — please still package the device as above.
If you need more information on our data recovery service, fill out the form with more detail about your issue and an engineer will review it and give you a custom quote.
We’ll be in touch shortly. For anything urgent, call 0117 332 1137.
The questions we are asked most about recovering a NAS unit.
Usually not. A crashed volume normally means a disk has dropped out or the Btrfs or ext4 file system is damaged, not that the data is gone. We image every disk, reassemble the SHR or RAID array and repair the volume to recover your shares. Don't let the NAS repair or rebuild it first.
Usually, yes. A NAS that won't boot has almost always failed at the box — the mainboard or power — while the disks inside are fine. Once you take the disks out and send them to us, we rebuild the volume off the box and recover your shares, so you don't even need the NAS working.
No — and please don't try. A NAS stores data on a Linux RAID volume with an ext4 or Btrfs file system, which Windows can't read, and it will offer to initialise or format the disk, which destroys the data. Bring us the disks and we'll rebuild the volume properly.
Yes, please — send every disk, including any that have failed, and note which bay each came from if you can. NAS recovery works by reassembling the volume from all the disks together, and even a dead disk often holds data we need to fill in the gaps.
Two-bay NAS mirror recoveries start at £500 + VAT. Multi-bay units — RAID 5, 6, 10 and SHR — start at £800 + VAT, depending on the number of disks and the work needed. Every job begins with a free diagnostic and a written quote, and most are no fix, no fee.
On most jobs, yes. For drive-level repairs we take a 50% deposit upfront and the rest is only due if we recover your data — so if we can't, you are not left with the full bill.
Every make — Synology, QNAP, Western Digital, NETGEAR, Buffalo, Asustor, TerraMaster, Drobo and the rest, every RAID level and SHR, ext4 and Btrfs. The make decides the method, not whether the data can be recovered.
Sometimes. NAS units are a common ransomware target, and where there are unencrypted files, snapshots or earlier versions left, we can often recover those. Ransomware that has fully encrypted the volume needs special handling, so ask us about that separately and don't pay anything before you do.
Usually, yes. A failed rebuild is the most common way NAS volumes are lost, because rebuilding writes to the disks. We stop, image every disk read-only and reconstruct the original SHR or RAID array from the copies, so a failed rebuild rarely means the end.
Most two-bay NAS units are done within 3 to 4 working days. Multi-bay units usually take 4 to 7 working days, depending on the number of disks and whether any need drive-level repair first. The free diagnostic is normally finished within 48 hours, and urgent business cases can often be prioritised.
Please take the disks out of the NAS yourself and send us just the disks — we don't remove drives from NAS or RAID devices ourselves. Label which bay each disk came from and pack them so they can't knock together. You can drop them off at our Bristol location Monday to Friday, 9am to 5:30pm, or post them to us fully insured. Include your name, address, phone number and email so we can book it in and quote before any work begins.
Free diagnostic, clear tiered pricing from £500 for multi-bay units, and no fix no fee on most jobs — every NAS recovered, Synology, QNAP and the rest, off the box. Start your recovery today.
