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,

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
