Is Your NAS Showing Any of These?
These are the most common signs our customers present with. If any match your situation, stop — and call us before taking any further action.
“Volume Crashed” or “Volume Degraded”
The NAS management interface shows the volume as crashed, inactive, or degraded after a drive failure. → Synology Volume Crashed guide
Failed or Stalled Rebuild
A drive was replaced and a rebuild started, but it stalled, failed, or made the situation worse. → NAS disk replacement rebuild failed
NAS Won’t Power On or Be Found
The device powers on but doesn’t appear on the network, or refuses to boot at all.
Multiple Drive Failures
Two or more drives have failed simultaneously — exceeding the RAID’s redundancy limit.
Power Surge or Firmware Update Failure
A power cut or routine firmware update has left the NAS in an inaccessible state. → QNAP RAID degraded / inactive
Accidental Deletion or Format
Files, folders or even an entire share were accidentally deleted, overwritten, or the NAS was reset.
Specific Failure Scenarios — Detailed Recovery Guides
Do not try to fix this yourself — it almost always makes recovery harder or impossible
Unlike standard hard drives, NAS RAID recovery requires precise reconstruction of disk order, parity rotation, and stripe size. A single wrong step can permanently overwrite the data structure. Common mistakes that destroy data:
- Running a RAID rebuild or reinitialisation through the NAS interface
- Swapping drives into a new or replacement NAS unit
- Using generic data recovery software on individual NAS drives
- Powering the NAS on and off repeatedly after a failure is detected

NAS Recovery Case Studies
Two real jobs, real outcomes — showing you exactly the kind of situation we recover from every week.
Synology DS1821+ RAID 5 Rebuild Failure — Architectural Practice, Manchester
A contractor replaced a failed drive and initiated a rebuild. A second drive failed during the process, then a partial DSM initialisation overwrote RAID metadata. All eight drives showed as “Not Initialised”. Data Clinic manually traced the correct disk order and left-symmetric parity scheme from raw data patterns, rebuilding the ext4 file system virtually.
QNAP TVS-872XT RAID 6 Offline After Firmware Update — Accountancy Practice, Leeds
A routine QTS firmware update corrupted the internal LVM volume configuration database. The NAS showed the volume as “inactive” with all 3.8 TB of client accounts and tax data locked away. Our engineers manually reconstructed the LVM mapping and RAID 6 parameters, mounting the ext4 volume read-only for safe extraction.
Frequently Asked Questions
Can data be recovered from a failed NAS?
Yes — in most cases. Even if your NAS won’t power on, shows volumes as crashed, or has had a failed rebuild attempt, professional recovery is usually possible. The key is stopping all use immediately and not making further changes before speaking to an engineer.
How much does NAS data recovery cost?
Cost depends on the RAID configuration, number of drives, and type of failure. Data Clinic provides a free initial assessment and exact quote before any work begins. Our No Data – No Fee policy applies to 2-disk NAS systems running RAID 0 or RAID 1 — call us to discuss your specific setup.
Is it safe to try recovery software on a failed NAS?
No. Running recovery software or a rebuild on a degraded NAS RAID can permanently overwrite parity information, making professional recovery impossible. If your data matters, call us first.
Do you support encrypted NAS volumes?
Yes — we recover from encrypted Synology, QNAP, and other NAS volumes where the encryption key is available. In some cases recovery is possible even without the key. Contact us to discuss your specific situation.
What should I do right now if my NAS has failed?
Power it down, do not reinitialise or rebuild, and do not move drives to another NAS unit. Call Data Clinic on 0800 151 2207 for immediate free advice — we’ll tell you exactly what to do next.

Data Clinic Ltd – Our Latest Trustpilot Reviews
Recovered External Drive
After an external hard drive failure on my home PC, Data Clinic successfully recovered my files and put them on a replacement drive. My experience with DC was excellent, all the staff I spoke to were efficient and helpful. I would 100% recommend Data Clinic.
My 1TB external drive drop on the floor…
My 1TB external drive drop on the floor at home and the drive heads got damaged and I take the drive to a company that I'm not going to mention they name but after they done the diagnostic test they to me to recovery the data would cost me £2400 and I told them no way then after I got back the drive from them they called me 2 days after and said they will drop the price from £2400 down to £1500 so that tells me that they wanted to scam or something and other companies prices was high and I didn't want to send my hard drive to different companies. Next day I googled and found Data clinic And the first phone call and the information they give me I was happy. The lady on the phone sent me a PDF File with a break down of all the prices for recovery and for hard drive repairs. They Recovered 90 to 95% of my files And the price I Paid Data clinic to repair my hard drive and to recovered the data and transfer to a new hard drive was cheaper than the first company that wanted to scam me . Data clinic price was lower than the £2400 and the £1500 . Data clinic services is on point and I would use them again if I have any issues and I would recommend Data clinic service 100%
Honeymoon pictures rescued
I dropped my "waterproof" phone in a swimming pool while abroad. Because I was roaming, nothing was backing up to the cloud, meaning the entirety of our honeymoon memories were trapped on the device. Thinking the phone was waterproof, I did everything you’re not supposed to do—I tried turning it on and plugging it in to charge. It overheated so badly that I was certain I had destroyed the phone and lost everything. Despite the massive damage I caused, the experts at Data Clinic managed to recover every single byte of information! The logistics were incredibly smooth. From my initial contact, they arranged a next-day courier and didn't take a penny in payment until they confirmed the device was physically in their hands. My only constructive feedback is regarding their communication during the actual repair. After that initial confirmation, things went completely quiet for about three weeks with no ETA. Handing over your phone and PIN to a third party requires a lot of trust, and the radio silence definitely made me worry. However, I really didn't need to panic. Out of the blue, they contacted me to say everything was recovered, and just 24 hours later, a memory stick arrived with all my data. Highly recommended, even if your phone seems completely beyond saving! Thanks Janice and Mohammed - you have been so pleasant and helpful. And thanks to the entire DataClinic team.
I cannot recommend this team enough
I cannot recommend this team enough. Chris and Janice and the team went above and beyond to help me retrieve data lost from my phone and as it was mostly charity work they even fixed my phone as a donation to the charity. I was so anxious and I am sure drove them mad with my questions and there were some issues backing up the data due to my settings but Janice was there calm and kind every step of the way reassuring me and they overcame every hurdle and everything was found. A 5 star personal, human and kind service which is rare but so talented and professional as well. Thank you all so much. Amazing customer service.
A very smooth experience from start to …
A very smooth experience from start to finish. I had a large music collection I thought I’d lost forever. I phoned them up and the process was clearly explained to me. They got my drive on the 4/8/26 and I got my data back on the 11/8/26. I got all of my data apart from one file that they reported was damaged so a fantastic result for me. Very reasonable price and very pleased with the quick service. The only negative was that the online payment system is not very mobile phone friendly and I had to call them to make the payment but apart from that i am super pleased I chose them. I would certainly recommend this company to everyone.
Brilliant service
Brilliant service. Janice and the lab team are outstanding. Good communication and updates throughout. Files on 2 discs were retrieved, 1 with new heads needed. Good pricing - transparent and competitive. They've been amazing. I wouldn't hesitate to use them again or to recommend them.
Communication was engaging
Communication was engaging. The services offered, potential cost and timescales were clear at the outset. The courier collection and delivery were managed well. A good experience and a positive outcome.
A very effective service
My iPhone completely bricked on holiday and I tried everything, even a new screen but I couldn’t get it to work. I thought I had lost all my holiday photos but Data Clinic managed to recover everything that was on the phone and I couldn’t be happier! They are very friendly and knowledgeable and the service is very in depth. They are honest and upfront about costs and will outline the whole process for you. I would definitely recommend instead of trying to take apart the phone yourself, it’s worth the money!
Highly recommend Data Clinic

Amazing service by the team and…
Amazing service by the team and especially Mohammad. My SSD was taken for emergency recovery within the same day and satisfactory results were delivered. Highly recommend these guys if you value your data!
Really satisfied with the service from…
Really satisfied with the service from start to finish. I've contacted multiple companies around Manchester which all quoted £400 - 700.00 with turn around time of minimum 1 week, where as they've completed this within 3 - 4 working days for less than £300.00 Huge thanks to Janice and the Tech team.
Top notch communication and service
Top notch communication and service. My hard drive fell onto the carpet and started beeping. My laptop registered a hard drive was connected but no files would appear. Janice at Data Clinic was amazing to correspond with via phone and email - she made the entire process from first phone call to receiving all files recovered on a new hard drive the following week (I paid for the priority service) as seamless as possible. Worth every penny. I highly recommend Data Clinic.
