Data Recovery · LanCologne

How can a company check, following a ransomware incident, whether data recovery is still possible?

Whether encrypted data can be technically reconstructed depends on the encryption method used and on whether any unencrypted remnants or shadow copies are still present.

Why this question is important

In the event of a failed or damaged storage device, the very first steps often determine whether data recovery is technically still possible at all. Hasty restarts, attempting to resolve the issue yourself using software, or incorrectly stored replacement parts can permanently worsen a situation that was originally recoverable. That is why a professional diagnosis is crucial before taking any further action – regardless of whether personal memories or business-critical data are affected.

Technical assessment on a case-by-case basis

We begin by analysing which type of encryption was used and whether there are any known implementation errors or original data that has not been fully overwritten. We also check whether any snapshots, shadow copies or residual backup data are still technically present on the storage medium.

What is realistically possible – and what is not

Provided that encryption has been implemented correctly and is up to date, recovery without the correct key is generally not possible given the current state of the art. There is a realistic chance of recovery primarily where there are errors in the encryption or where residual data has been preserved outside the encrypted area.

Why LanCologne?

When a data storage device is damaged or has failed, one thing is paramount: the data must not be put at further risk by the recovery attempt itself. This is precisely where our approach comes in.

As a team with a background in IT forensics, we are accustomed to handling data storage media in such a way that data structures are not unnecessarily overwritten or destroyed. This care also benefits traditional data recovery, regardless of whether an expert report or simply the recovered files are required in the end.

Every data recovery job we undertake begins with a free initial assessment. Only once the cause of the damage has been technically identified will you receive a written quote setting out the estimated cost. You can then take your time to decide whether to accept or decline this quote – with absolutely no obligation.

For the actual data recovery process, we use professional systems where the specific cause of the damage requires it, such as the PC-3000 platform and the DeepSpar USB Stabiliser for damaged or unstable hard drives, PC-3000 Flash for firmware and chip-level repairs on SSDs and flash storage, as well as R-Studio and UFS Explorer for RAID and file system reconstruction. The diagnosis determines which tool is appropriate in each individual case – not a standard procedure.

No reputable professional can guarantee success without first examining a physically damaged data storage device. What we can promise is a meticulous, transparent process carried out in our own laboratory in Cologne, including, where necessary, a cleanroom environment for opening the storage medium – without your storage medium being dispatched or passed on to third parties.

Our process

1Initial contact and description of the problem.
2Secure transport or personal delivery of the data storage medium to our laboratory in Cologne.
3Free initial technical diagnosis to identify the cause of the damage.
4Determining whether the fault is logical, mechanical, electronic or firmware-related.
5A written quotation setting out the work involved and the costs, with no obligation to place an order.
6Once you have given your approval: carefully back up the raw data using suitable hardware or software.
7Where necessary, repair or work around faulty components, firmware or controller issues.
8Reconstruction of the file system, partition structure or RAID array from the backed-up raw data.
9Checking the recovered data for readability and completeness, insofar as this can be determined technically.
10Confidential transfer of the recovered data to a storage medium of your choice.
11Upon request, the original data carrier will be returned or destroyed in accordance with best practice.
12Invoicing in accordance with the previously accepted written quotation – not before you have given your approval.

Free assessment, a transparent quote – and honest limitations

The initial consultation is always free of charge at our practice. Only after this will you receive a clear, written quote, which you are free to accept or decline without incurring any costs.

What we do not do is promise a success rate or a guarantee of recovery before the storage device has been examined. The condition of read/write heads, memory chips, controllers and file systems varies so greatly from case to case that reliable assessments can only be made once a diagnosis has been carried out. This caution is part of our ethos as a team with a forensic background: we communicate only what is technically verifiable – no more and no less.

Sensitive content – whether private photos, business documents or client-related data – is treated confidentially by us and is not passed on to third parties.

Frequently Asked Questions

Can you guarantee that the data recovery will be successful?+
No. A reputable data recovery service cannot guarantee success before carrying out a technical diagnosis. Following the free initial analysis, we will outline what is realistically possible from a technical point of view.
How much will the data recovery cost if I decide not to accept the quote in the end?+
The initial diagnosis is free of charge. If you decline our written quote, you will not be charged for the diagnosis.
Will my personal data be treated confidentially?+
Yes. Your data is processed exclusively in our own laboratory in Cologne and is not passed on to third parties.
Why does a forensic background play a role in „standard“ data recovery?+
Because the same careful, non-destructive handling of data storage media that we are familiar with from IT forensics also prevents any attempt at data recovery from exacerbating the original damage in traditional data recovery.
