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.

Accidental re-sync / rebuild started

Power down immediately to limit write-back. We can often salvage from remaining members.

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)

  1. Free evaluation & protection: Document NAS model, RAID level, slot order, encryption, and prior attempts.
  2. Member-by-member imaging: Write-blocked cloning of each disk (PC-3000/DeepSpar). Donor parts for mechanical members when needed.
  3. Metadata capture: Copy RAID headers/superblocks, record stripe sizes/parity rotation/offsets.
  4. Offline reconstruction: Assemble the array from images only. Validate parity and file system integrity.
  5. File system & data recovery: Rebuild/correct the FS on the clone, carve where needed, verify priority shares/VMs.
  6. Deliver & purge: Copy to target(s), verify with you, and securely purge working copies on request.
Typical timing: 2-4 member arrays with healthy reads: a few days. Larger arrays or weak/failed members: days-weeks.

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).

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 recover data from the images.
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.
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.
How long does RAID data recovery take?
Small arrays (2-4 members) with healthy reads: a few days. Larger arrays or weak members: 1-3+ weeks.
Do you need my entire NAS chassis?
Usually just the drives (labeled with slot order) and any encryption keys. Bring the chassis only if the vendor uses on-device encryption.
How is RAID recovery priced?
Per-member imaging for logical/firmware issues, array reconstruction line item, and mechanical member work only when needed. 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.
