RAID Data Recovery
RAID 0/1/5/6/10, Synology & QNAP NAS
We recover failed arrays with an image-first workflow: member-by-member imaging, offline reconstruction, and recovery from the clone. Free evaluation. No data = no charge. All work performed in-house at our Austin lab.
Common RAID & NAS Symptoms (and what NOT to do)
Degraded array
Do not force a rebuild on failing members; this can destroy parity and metadata. Power down and stop writes.
Volume crashed / Uninitialized
Do not accept prompts to repair/recreate. Initialization overwrites critical metadata.
Multiple disk errors
Avoid swapping order or repeated hot-plugs. Label drives and preserve original order.
Clicking/slow members
Do not keep power-cycling; heads may be weak. Each cycle risks surface damage or firmware degradation.
Accidental re-sync / rebuild started
Power down immediately to limit write-back. We can often salvage from remaining members/images.
Encrypted volumes
Have keys/passwords available. We keep data offline and under chain-of-custody during work.
Important: Any write activity (rebuilds, "repairs", new shares) can overwrite recoverable data. Power down and contact us.
Our RAID Recovery Process (Member-First, Image-First)
- Free evaluation & protection: Document NAS model, RAID level, slot order, encryption, and prior attempts. No experiments on the originals.
- Member-by-member imaging: Write-blocked cloning of each disk with head-maps and conservative retries (PC-3000/DeepSpar). Donor parts for mechanical members when needed.
- Metadata capture: Copy RAID headers/superblocks (mdadm/ZFS/Btrfs/XFS/NTFS), record stripe sizes/parity rotation/offsets.
- Offline reconstruction: Assemble the array from images only. Validate parity and file system integrity; never rebuild on failing members.
- File system & data recovery: Rebuild/correct the FS on the clone, carve where needed, verify priority shares/VMs.
- Deliver & purge: Copy to target(s), verify with you, and securely purge working copies on request.
Why Rossmann for RAID & NAS Recovery
Image-first, offline reconstruction
We never rebuild risky arrays in place. Everything is assembled from clones for safety.
Top-tier tooling
PC-3000/DeepSpar imaging, HBA passthrough, mdadm/ZFS/Btrfs understanding, R-Studio/UFS Explorer.
Transparent pricing
Clear ranges by member count and condition. If it’s easier than expected, you pay less.
Direct engineer access
Straight answers from the person doing the work; no scripts, no sales middlemen.
No evaluation fees
Free estimate and honest likelihood of success before paid work begins.
No data, no charge
If we can’t recover usable data, you owe $0 (optional return shipping).
Watch Real Recoveries
Common Questions; Real Answers
Can you recover a Synology or QNAP that says “Volume crashed”?
Often, yes. We image each member with write-blocking, capture RAID metadata, reconstruct the array offline, and then recover data from the images. We do not attempt risky in-place repairs or rebuilds on your original NAS.
Should I try a RAID rebuild if it’s degraded?
No. Forced rebuilds on failing members can destroy parity and metadata. Power down and avoid writes. We’ll stabilize access and image each member safely before any reconstruction happens.
Two drives failed in my RAID-5. Is there any chance?
Sometimes we can recover partial data if failure timelines overlap favorably or if one member is only marginally degraded. It’s case-dependent; imaging quality and prior attempts matter most.
How long does RAID data recovery take?
Small arrays (2-4 members) with healthy reads take a few days. Larger arrays, weak members, or mechanical work extend timelines to 1-3+ weeks, especially if donor parts are required.
Do you need my entire NAS chassis?
Usually just the drives (labeled with slot order) and any encryption keys or credentials. Bring the chassis only if the vendor uses on-device encryption or model-specific metadata we need to access.
How is RAID recovery priced?
We price transparently: per-member imaging for logical/firmware issues, an array reconstruction line item, and mechanical member work only when needed. If it’s easier than expected, you pay less. If we recover nothing, you owe $0.
Can you sign an NDA / handle HIPAA data?
Yes. Your drives remain in our Austin lab under chain-of-custody. We routinely sign NDAs and BAAs. Working copies are securely purged after delivery on request.
