Data recovery

What data can be recovered?

Firstly, whatever has happened, there is a very good chance that your data is recoverable.

When you find yourself in a data loss situation, it can be very worrying that critical data, research work or personal information may have gone forever.  In the vast majority of failures, this is simply not the case. We are able to recover from almost any media from the vast majority of problems, including clicking, fire or water damaged media, broken memory chips, deleted files, etc. etc.

For hard drives we can strip down and completely rebuild, we can re-program the microcode used to make the drive funtion.

On Failed RAID systems we can rebuild using the most advanced software and hardware.

For lost data on memory cards we can work at the board level to extract data directly from the memory chips.

Logical Problems

Failed RAID

Electronics issues

Dead SSD

Head crash

Firmware problems


Seized hdd motor

Unreadable tape

Logical problems

We can recover data from media that has deleted or missing files and media that has been formatted. Also, we are able to recover files that are showing as zero byte size such as outlook pst files and even VMs and Exchange and SQL databases - this typically happens after chkdsk has run or there was a power outage while the files were live.

Firmware issues

Sometimes a hard drive or SSD will stop working because there are firmware issues in the drive. We are able to access the factory information on the drives and repair and work around firmware problems, sometimes reprogramming the microcode to get the drive into a readable state.

Electronics issues

When a hard drive or SSD has failed, it may be an electronic problem, for example a short circuit or component failure on the circuit board (PCB) . We identify the failed components, repair or replace and get access to the data. For hard drives, this can be a complex issue because of unique information stored in ROM memory on the PCB, so a copy of the ROM is made and stored safely before any remedial work is made to the PCB.

Mechanical failures

When a hard drive suffers a mechanical failure such as a head crash or motor seizure, we need to open the drive, determine exactly what has failed, repair or replace the faulty components and set about recovering your data. All work is carried out in a ESD safe Class 100 clean air environment.

Chip off recovery

If a memory card or SSD has failed and is not recognised by the computer we can recover data directly from the memory chips. We use the latest equipment and up to date software to recover from dead memory cards.

For the small micro SD cards used in cameras and phones, we either have special adapters made or in many cases we can manually wire the devices to enable us to read.

Have you been told your data is not recoverable?

If you have been told your data is not recoverable by another data recovery company or computer workshop, we are always ready to give it a second opinion, in the majority of cases with no diagnostics charge!

Sometimes a misdiagnosis can make it appear that data is not recoverable, where with the correct diagnosis and repairs it is possible to recover. For example, we are able to access the FW on many drives where other companies can not.

We also have advanced methods of reading and extracting from deleted data, or files that even show as 0 bytes.

Definition of data recovery.

Data recovery means: restoring access to inaccessible data.
This is achieved by diagnosing and repairing damaged computer storage media; Searching for missing or deleted files and identifying corrupt files and folders; then extraction of the recovered data to a safe storage media.

Diagnosis and analysis is the most important part of the data recovery process. Any failure to assess the media device or data corruption correctly can result in failure or delays in recovering the data.

Assuming a fault and applying the procedure based on that assumption can make the situation worse. For example, applying a firmware fix when it was not necessary, opening a drive outside a cleanroom, etc. Good analysis procedures mean correct identification of the faults so the correct procedures can be applied.

Data recovery process

Every job we do follows the same primary process. Further sub processes and diagnoses are performed depending on the faults found during the initial diagnosis and further analysis stages.


1. Determine the faults to the storage media or data that caused the problem. If it's a physical problem we make repairs, often in our Class 100 clean-room ensuring that data remains safe throughout the recovery process.


2. Cloning and recovery. The first part of the recovery plan always involves making a clone of the failed device - no matter what the problem is. This gives us a working copy of the data meaning your media is not used for the remainder recovery plan.


3. Testing the data. We have proprietary software that generates a file list of the data that has been recovered. The file list shows you every file with the status of its content, once you have determined your data is recovered, we move on to the final stage...

Return delivery

4. Copy the data ready for despatch. Your data is copied to return media ready for despatch. If your data contains sensitive information or data covered by NDA, DPA or GDPR regulations, this return media can be encrypted.

Service levels to suit all budgets.

Non urgent service

Our non-urgent service is for customers where there is no urgency on the turnaround of the data making it an economical service. Typical timescales are up to 14 days, often quicker.

Priority service

Our priority service is for customers who need their data back urgently, your job takes priority over standard and non-urgent work. You critical data is targeted first to get you back up and running.

Standard service

Our standard service is for customers where a tighter turnaround is required. Typical timescales are 3 to 5 days, depending on the volume of data and complexity of the problem.

Emergency weekend service

The emergency service means your media is worked on around the clock until your critically important data is ready.

Remember, our prices include everything, spare parts where required, return media, all labour costs and return delivery within the UK. You will not get any unpleasant surprises as you do with some other companies.

We always aim to keep within the timescales we quote for. Over 95% of our work is completed on time or sooner. If we hit any snags, we will contact you to let you know and give an updated timescale.
