NAS Data Recovery you can trust

NAS boxes fail in ways a single drive never does — crashed volumes, degraded arrays, and proprietary file systems. We recover NAS units from every major maker, priced per case after a free evaluation.

About nas data recovery

Most consumer and small-business NAS units run Linux. Behind the vendor's interface, drives are usually combined with Linux software RAID (md), often with LVM on top, and formatted with ext4 or Btrfs, while some systems use ZFS. Vendors add their own layers as well. Synology Hybrid RAID, for example, splits mixed-size drives into partitions and builds several md arrays that are joined into one volume. Recovering a NAS means reassembling each of these layers correctly, from the raw drives up to the shared folders.

NAS units fail differently than single drives. A volume may crash after a drive drops out, a power cut can interrupt writes and leave the file system inconsistent, or a firmware update can fail partway. Because many NAS boxes run around the clock for years, drives bought together often wear out together, so a second drive can fail while the first is being replaced. Accidental resets and reconfiguration through the admin interface are also common, and some of those actions write new metadata over the old array.

A NAS that won't boot, or that reports a crashed volume, very often still has its data on the drives. Because the storage layers are standard Linux components underneath, the volume can usually be rebuilt from drive images without the NAS enclosure itself. What matters most is that the drives haven't been reinitialized or rewritten since the failure.

What we recover

  • ✓Synology, QNAP, Buffalo, Netgear, WD, Drobo
  • ✓Crashed and unmountable volumes
  • ✓Degraded and failed RAID/SHR arrays
  • ✓Shared folders, backups, and surveillance data

Common failures we handle

  • •Volume crashed or is read-only
  • •One or more member drives failed
  • •NAS won’t boot or beeps
  • •Accidental reset, delete, or reconfiguration

Before you send it in: what not to do

  • ✕Don't run the NAS repair or rebuild wizard on a crashed volume — it can resync parity over the data you need.
  • ✕Don't reinitialize the NAS or reinstall its operating system with options that erase data — these can create new volumes over the existing ones.
  • ✕Don't connect the NAS drives to a Windows PC — Windows can't read the Linux volumes and may prompt you to initialize or format them.
  • ✕Don't remove drives without labeling their bay numbers — the order matters when rebuilding the arrays.
  • ✕Don't keep writing new data to a degraded volume — every write stresses the remaining drives and can overwrite recoverable data.

How we recover it

1

Record the setup

We note the NAS model, the bay position of each drive, and what you know about the volume type, and evaluate each drive's condition.

2

Image every drive

All member drives are cloned individually, with failed drives repaired first, so the originals are never written to.

3

Reassemble the storage stack

From the images, we rebuild the md-RAID arrays, LVM volumes, and vendor layers such as SHR in the correct order.

4

Repair the file system

We read the ext4, Btrfs, or ZFS volume directly, using older metadata copies or snapshots where the current structures are damaged.

5

Extract and verify

We recover shared folders, backups, and surveillance footage, check critical files, and return them on a secure return drive.

NAS Data Recovery — common questions

How much does nas data recovery cost?+
Multi-drive cases are quoted per job after a free evaluation — the price depends on the configuration, the failure, and the work involved. There's no charge for the evaluation, and you pay nothing unless we recover your data.
Should I send the whole NAS or just the drives?+
The drives are what we need, each labeled with its bay number. The enclosure is rarely required, because the volume is reassembled from drive images. If you used encrypted shared folders or volume encryption, include the password or key file, since the data can't be read without it.
My Synology says the volume has crashed. Is the data gone?+
Usually not. A crashed status generally means one of the underlying RAID or file system layers can't be assembled or mounted, not that the data has been erased. Recovery depends on the drives' condition and on whether anything was rewritten afterward, such as a repair attempt or a reset.
Can you recover data after the NAS was reset?+
Sometimes. It depends on what the reset did. Some resets only change system settings and leave the volumes alone, while others create new volumes and file systems, which overwrites existing metadata and possibly some data. We assess what remains during the free evaluation.
Is my data still recoverable?+
In most cases, yes. A device that won't boot or mount usually has a hardware fault while the data itself is intact. The key is to stop using it — don't reformat, rebuild, or keep powering it on — and let our cleanroom handle it.
How do I send in a NAS system?+
Start online for a free evaluation and we'll arrange secure, insured shipping. Your system is assessed in our cleanroom, you approve a fixed quote before any work, and you only pay on a successful recovery.
How long does it take?+
Most cases are evaluated within a couple of business days of arrival, with a turnaround estimate provided alongside your quote. Emergency service is available when time is critical.
