NAS Data Recovery
Synology, QNAP, Drobo, and WD NAS enclosures with failed RAID arrays, unresponsive units, or corrupted filesystems. We image every drive before touching the array configuration — protecting you from the failed rebuild that destroys everything.
Do not start a RAID rebuild. A failed rebuild on a degraded array permanently destroys parity data. Power off and call us first.
NAS Recovery Scenarios
Failed RAID Rebuild
A RAID rebuild that stalled, threw errors, or corrupted the array is the most dangerous situation — and the most common. We image all drives first before any reconstruction attempt.
Multiple Drive Failures
RAID 5 arrays with two failed drives, or RAID 6 with three — we reconstruct from surviving members and parity data using virtual RAID rebuilding tools.
NAS Won't Boot / Unresponsive
NAS firmware failure, corrupted OS partition, or failed boot drive. We access the data drives directly, bypassing the NAS operating system entirely.
Filesystem Corruption (Btrfs / ext4)
Synology DSM, QNAP QTS, and other NAS systems use Linux filesystems. We repair or bypass corrupted Btrfs and ext4 file systems to recover your data.
Accidentally Deleted Shares
Deleted network shares, users, or entire volumes on a NAS. Data is often still present in unallocated space. We image and reconstruct before anything overwrites it.
NAS Dropped / Physical Damage
Knocked a NAS off the shelf? We assess each drive individually for physical damage before any reconstruction attempt — a damaged drive in a RAID rebuild can destroy the array.

FAQ
Why is NAS recovery more complex than regular drive recovery?
NAS arrays use RAID across multiple drives and proprietary Linux filesystems (Btrfs, ext4, XFS). Recovery requires reconstructing the RAID parameters (stripe size, drive order, parity rotation) virtually before any file system work can begin. Getting these parameters wrong destroys data permanently — which is why we image first and reconstruct in a controlled environment.
Can you recover from a Synology NAS with degraded RAID?
Yes. A degraded array (one failed drive in RAID 5, for example) still has all data accessible. We image the failed drive first to attempt recovery from it, then reconstruct the array virtually. We have a very high success rate on single-drive Synology RAID 5 failures.
Should I try to add a replacement drive and let the NAS rebuild?
Not yet. If the RAID rebuild fails (e.g., due to read errors on a degraded surviving drive), you can end up with a completely broken array. Let us image all drives first and assess their health — then we can advise whether a manual rebuild is safe or whether we should do a virtual reconstruction in our lab.
How much does NAS data recovery cost?
NAS recovery pricing depends on the device and required service for simple logical failures and scales based on the number of drives, RAID level, and extent of physical damage. Multi-drive physical failures are at the higher end. We provide a firm quote after imaging all drives.
