R3 Data Recovery is a leading UK data recovery service specialising in the recovery of lost data from failed RAID arrays, Server arrays and NAS devices. Our experienced, United Kingdom-wide Response team is available 24 hours a day, around the clock, for the purpose of emergency data recovery of critical systems.
The Security House lab is central to the successful story of R3. It was first developed in 2007 as the UK’s first high-capacity data recovery operation. R3 are one of the UK’s leading data recovery labs providing services through IT Support Companies, PC Shops, our partner network of data recovery and disaster recovery managers, and direct to home users, self-employed professionals, and students.
We serve clients across the United Kingdom with locations in London, Birmingham, Bristol, Glasgow, Leeds, Liverpool, Newcastle, Northampton, Sheffield, and Southampton – ensuring you’re never far from expert assistance.
In recent data loss situations, R3 Data Recovery has recovered data from many failed server systems and RAID arrays where the unimaginable has happened and the IT department’s worst fears have been realised. Some of those scenarios are listed below:
In the case of failed hard drives that require attention, our ISO 3 (greater than class 100) certified Cleanroom labs are situated around the country, so you are never far away from a full recovery of your data.
No server or RAID (Redundant Array of Inexpensive Disks) system is entirely resistant to failure—hardware and software components can fail unexpectedly. Whilst it is true that most RAID levels provide good data redundancy against failure, allowing for one failed disk (as in RAID 5 arrays) or two failed disks (as in RAID 6 arrays), the fact remains that there is absolutely no guarantee that irregularities in the power supply, sudden knocks or impacts, human error, or even natural disasters will not lead to the loss of data from what was thought to be a secure system.
Common risks include:
Data recovery services and dedicated data recovery personnel must exist as a fallback for when the worst does actually happen! R3 Data Recovery exists for that very reason—we specialise in RAID Data Recovery, server recovery, and offer emergency service options to ensure that you are back up and running, with all of your data intact. In most cases, other than minimal downtime, you would not be aware that the data had been lost.
Our technology and expertise mean we can recover data from virtually any RAID storage system, providing complete peace of mind and excellent customer experience throughout the process.
R3 offer recovery of all RAID Arrays and File Server systems regardless of the configuration, the nature of the file system, or the operating system that was used to create the data.
Our current research indicates that there are no file systems we are not able to support. Whether your documents are stored on a Windows server, Linux Database system, or macOS environment, we have the tools and expertise to help.

RAID arrays form by far the most popular modern method of storing data in business environments, from small office NAS devices to enterprise-level data storage device configurations.
Originally designed with two factors in mind—more reliable data storage (through redundancy, which does not apply to RAID 0 or spanned arrays) and an increase in throughput performance, i.e. far quicker operation than a single drive.
Key RAID concepts include:
There are dozens of different RAID configurations, known as levels. The type of application, the storage requirement, scalability, expandability, and performance are all factors which will dictate the best RAID level to implement. RAID 30 for high-speed video editing, RAID 1 for metadata and log storage, and RAID 5 (possibly the most common level configured) for all-round use.

We try and answer your most important questions straight away so you’re left with the full picture of exactly what we do and how we do it.
The likelihood is yes, we probably can. For RAID systems our current success rate is above 95% for a full recovery, provided the RAID has not been subject to numerous manual rebuilds or recovery attempts by the user or IT admin.
For single hard drive failures, our success rate varies depending on the type of failure, as well as the manufacturer of the drive (certain drives have known issues, which can reduce the chance of successful recovery). Generally, we enjoy success rates above 98% for single drives.
Roughly, single hard drives cost from £375 plus VAT. The price will rise depending on the capacity of the drive, and the nature of the failure.
For RAID systems, pricing is worked out on a per-job basis, as there are far too many variables that prevent publishing of pricing structures.

If you are local to us, you may make an appointment to deliver your device. Alternatively, you can use any reliable courier service. If you have a large and fragile storage device, such as a complete server, we recommend using a dedicated, same-day courier.
The chances are you have not actually lost your data – it has merely become inaccessible. The services of a data recovery professional will usually be able to restore access to the lost data. It is critical you do not attempt DIY data recovery, as this all too often results in catastrophe.
Please contact us for more information.
The only sure-fire way to prevent data loss is to have a comprehensive backup routine in place. This backup system needs to be tested regularly; we often encounter users who have been backing up religiously – but the backups have all failed.
Even your backup system should be backed up, and the backup taken off site. Learn not to trust any storage medium on its own – all storage systems can fail.
If a single hard drive fails and is making any odd noises, it’s important to power the drive off, and leave it off until you can get it to a data recovery professional. Further attempts to read the drive or copy off data will almost certainly cause further damage to the drive, and may well render it completely unrecoverable. This can occur if there is a failure of the read/write heads; allowing the drive to continue spinning could result in the damaged heads scratching the platters, leaving absolutely no chance of recovery.
With RAID, there are more options. Many causes of failure are the result of a crashed RAID rebuild (following swapping out a failed drive with a healthy one). At this point, you need professional assistance. A power surge can leave more than one drive damaged – enough to bring down the RAID. This needs immediate professional attention.
