RAID Data Recovery Services UK
Got a crashed RAID array? Call now to find out how our RAID data recovery engineers can regain your lost data the same or next day.
RAID stands for Redundant Array of Independent Disks (originally Inexpensive Disks). It's a technology that combines two or more hard drives for greater performance and reliability of data. RAID has different levels (see below) designed for increased reliability and faster input and output. Our RAID array recovery service covers every level. For a single failed drive, see our hard drive data recovery service, and for network storage our NAS data recovery service.

RAID array degraded, offline, or rebuilding failed? Every minute counts.
Whether it's a failed RAID controller, multiple drive failure, or a botched rebuild, continued use can turn a recoverable fault into permanent data loss. Power the array down now and let our RAID data recovery engineers run a free RAID recovery evaluation before you risk anything further.
RAID Data Recovery
RAID levels are implemented either in software, by the operating system, or in hardware, by a RAID controller. Hardware RAID is the most common. Because a RAID array is made up of two or more drives, a failure increases the complexity of data retrieval compared with a single disk, which is why RAID server recovery needs specialist engineers.
Disk Doctors' RAID data recovery experts are certified by Adaptec and can often recover your data even when other attempts at retrieval have failed. We specialise in all available RAID arrays, regardless of array size, configuration, operating system or platform. RAID data recovery is one of the most complex recovery processes we perform routinely. Our engineers take such jobs as a challenge and will get your data back as far as possible.
If the failed array is a server, our VMware data recovery, Hyper-V data recovery and Exchange server data recovery teams can also recover the virtual machines and mailboxes stored on it. Based in London? See our RAID data recovery London service.
RAID Failure Situations
RAID failure has many causes, but our experience since 1991 shows that most failures are made worse by human error. A "let me try myself" attitude, such as forcing a rebuild or swapping drives around, often complicates RAID recovery.
Our Data Recovery Process
Our data recovery process is secure, transparent, and designed to minimise downtime. Here's how it works:
Send us your device using the free postage label and our engineers will assess it for free. We'll let you know exactly what's recoverable before you commit.
We create a full, bit-by-bit clone of your storage media to preserve the original. Your data remains untouched while we work on the image copy.
Depending on the fault, we use cleanroom hardware repairs or forensic software tools to extract your data, even from damaged or encrypted media.
You'll receive a file list of everything we can recover. Once approved, we'll return your data on a secure USB drive or via encrypted cloud transfer.
Prices
As no two data recovery situations are identical, it is impossible to give a fixed price without the initial FREE evaluation. Generally speaking, for RAID server recovery, the price range starts from £199, and your RAID data recovery cost is confirmed after the evaluation. Emergency services are available 24/7 at a premium.
RAID Recovery Turnaround Time
Disk Doctors will put all its resources to recover your valuable data as fast as possible. As every situation is unique in RAID data recovery, delivery time and recovery cost can not be determined until the server is evaluated. The free evaluation is started as soon as we get the server or drives. Depending upon condition and number of the drives in a raid server; in most of the cases evaluation will be done within 3 to 6 hours of receiving the media. A typical RAID data recovery turn-around time including free evaluation is usually between 3 hours to 48 hours. Some server can take more time.
Rush Service is also available on RAID servers at a premium. This means our emergency RAID recovery engineers will work 24/7 and try their best to finish as soon as possible; which may be done in as little as 1 to 2 business days.
