RAID Data Recovery

The word RAID comes from Redundant Array of Inexpensive Disks. It’s a technology which allows integrating two or more hard drives for greater performance and reliability of data. Raid has different levels (see below) specifically meant for increased reliability and increased input and output of data.

The RAID levels are implemented by software in the operating system and hardware. The hardware type is most common. Since Raid consists of two or more drives, its failure increases the complexity of data retrieval as compared to a single disk.

Disk Doctor RAID data recovery experts are certified by Adaptec and can recover your data even if all other means of retrieval have failed. We specialize in all available raid arrays regardless of the array size, configuration, operating system, or platform of your Raid Array. RAID Data Recovery is one of the most complex recovery processes that we perform at Disk Doctors routinely. Engineers at Disk Doctors take such RAID jobs as a challenge and will get your data back as much as possible.

Raid Failure Situations:

RAID failure is due to many factors but our experience over a decade shows that most of failures have been aggravated by human error. “Let me try myself” attitude often complicates the recovery of RAID.

Common Raid Failures Service Options

  • RAID Controller failure
  • Raid configuration lost
  • Accidental reconfiguration and initialization of RAID array
  • Multiple drives failure
  • Raid partition missing
  • Virus Damage
  • Partition was formatted
  • Raid drives have mechanical fault

Expert tips!!! Service Options

  • Never reinitialize drives
  • Never change the sequence of the Raid Drives
  • Do not reinstall Operating system
  • Do not create new partitions
  • Immediately switch off Raid drives upon hearing unusual sound from the Raid drive
  • Label all drives according to their position in Raid Array
  • Always seek professional help Call Disk doctors at 0800 043 6611

Raid Data Recovery Process:

Raid Data Recovery Process: Disk Doctors Lab has recovered thousands of servers over the years. Data Recovery process for Raid starts from an initial FREE evaluation stage. Our engineers treat every RAID recovery as a priority. Once the server or drives reach our lab, our engineers will evaluate them and find out the exact issue with the raid array. In the evaluation process, we will determine whether RAID has logical corruption to the array structure, or the drives in the RAID array have suffered any physical damage. Once the cause of failure is determined our Raid engineer will send you a report along fixed quotation for your approval.

Once approved the recovery begins, in the case of logical corruption, our engineer will make a raw sector by sector image onto Disk Doctors' storage media, and then destripe the array using proprietary tools (software and hardware). This process can be repeated several times to get better result.

In case of physical damage to a drive(s), each drive will be taken to Class 100 Clean Room and fixed, and then raw image will be taken, then destripe process will be done on the whole raid array.


As no two data recovery situations are identical, therefore, it is impossible to give a fix price without the initial FREE Evaluation. Generally speaking, for RAID server recovery, price range starts from ÂŁ199. Emergency services are available 24/7 at premium.

Turn around 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 premium; this means our RAID data recovery engineers will work 24/7 and try their best to finish it as soon as possible; which may be done in as little as 1 to 2 business days.

Data Protection & Confidentiality

Disk Doctors guarantees protection of your data throughout the data recovery process, from evaluation to handing data back to the client.

  1. Disk Doctor Employees are selected through a rigorous process of selection and follow our strict rules and procedures for handling the client data.
  2. Client media is cloned sector by sector onto our own lab media and all the data recovery work is carried out on the cloned media not the original media; this ensures that client’s storage media is always intact.
  3. Upon successful recovery Disk Doctors by default keeps a copy of the data for 7days before it gets deleted automatically from our Lab Server. This helps in providing the copy of data again if some thing goes wrong during the transfer of data to client e.g. the data media gets damage or goes missing during the postal process.
  4. Our agreement to recover the data includes the clause for protection and non disclosure of data as per legal rules and regulations. If you require separate agreement for data protection and non disclosure, we are happy to sign the agreement.

To recover your loss data we follow a standardized data recovery process in all our data recovery labs across the globe. Call us at 0800 043 6611 to consult your case or submit your case for free evaluation with No Recovery, No Charge guarantee.

I was very happy with the service and professionalism I encountered when dealing with your company. The options available, the quick turnaround & correspondence updating me with the progress of my call were all above my expectations and I have already recommended your service to colleagues.

While I hope I don’t need such help in the future – any HDD issues I can’t fix will be coming your way.
Many thanks,

Hope that helps

You service was good – obviously an efficient e-mail run system is in place. One criticism though I took the trouble to point out the specific area where the PST files needing recovery were to be found but this was ignored and the wrong files recovered. it was only when I insisted that they were where I said they were that you did indeed find and recover them. As you pointed out at the start we had used another recovery company first who had failed to restore the files we wanted and on further inquiry insisted it was not possible to do so – so hats of to Disk Doctor. We will use you again if we need to.
I was hugely happy with the work you managed to save from my hard drive. I have lost quite a few photos but that is NOTHING when I consider you got all of my work files back to me safely - that is truely the MOST important thing.
I found Shakeel very helpful and lovely And I was so pleased you adjusted the price. I was desperate from my information to be found but I had little chance of paying the first quoted fee.
I thank you and would highlyu recommend your service to anyone else.
All the best
