data recovery

You can call on us as an individual or as a business. We maintain high service standards for all our clients. We apply the same process throughout, and we only give up on a recovery once every option available to us has been exhausted.

You can visit us at 20-22 rue Louis Armand, 75015 Paris, request a collection anywhere in France by calling us on 01 40 60 00 00, or use a courier.

You have nothing to pay during the free assessment (except for SSD drives and phones). Payment is due once we ship or transfer your data back to you, at the end of the recovery. We only proceed with the recovery once you have accepted the quote.

Data recovery (or data restoration) means retrieving data lost from storage media due to hardware failure, an accident (impact, electrical fault, fire, flooding, etc.), malicious action or human error. How difficult the recovery is varies widely depending on the type of fault. The simplest faults are logical faults. Mechanical faults can be a real technical challenge.

Recovering data from a media, whether a hard drive, magnetic tape or otherwise, breaks down into four stages.
Repairing the media:
Whether it is a USB key, a hard drive or an SSD, repair is the first step. Often temporary, repair relies on costly hardware solutions generally carried out by specialists.
Bit-by-bit copying of the media’s contents:
This stage relies on either a hardware solution (for example a Deepspar disk imager) or a software solution (for example dd_rescue on Linux). Depending on the media, some options are more effective than others. The aim is to then work on a copy of the media rather than the media itself, so as to put as little strain on it as possible and avoid destroying it for good.
The actual data recovery:
This is a software-based approach. These are typically the best-selling solutions on the market, ranging from simple partition recovery to full data recovery.
Repairing corrupted or unusable files:
This last stage is done either by hand or with software. It is a very important activity for companies working on digital forensic evidence.

Restoring deleted files is possible because the operating system organises the resources it accesses and finds them again via an index. On a hard drive, for example, the system refers to the files it needs this way, much like a table of contents for a book. This index is independent of the files physically present on the disk. Deleting a file therefore amounts to removing an entry from the table of contents, without actually tearing out the corresponding page. As long as our files are not overwritten, they can generally be restored.
