Étude de cas : Récupération de données sur clé USB

Le 64GB Lexar flash drive sustained electrical damage when it was bumped while still plugged into the laptop. The sudden force caused electrical components in the device to fail, affecting the internal controller that manages the writing and accessing of data stored on the NAND flash memory. This rendered the drive unreadable.

Despite being a common issue, most local repair shops lack the advanced tools and knowledge necessary to recover data from such failures, leaving customers with seemingly no options for recovery.

Lorsqu'un flash drive suffers from an electrical failure, it can be due to damage to the controller chip, which is essential for the data on the drive to be accessed with any system. In this case, the impact against the door frame likely caused the controller chip to fail, making traditional data recovery techniques ineffective.

To bypass the failed controller, the data recovery engineers at DriveSavers performed a “chip-off” procedure. This involves physically removing the memory chips from the damaged drive and accessing the raw binary data directly from the flash memory itself. This method allowed the engineers to use a series of mathematical operations to reinterpret the raw data into recognizable files without relying on the device’s broken controller.

Utilisation advanced, highly specialized tools and techniques, DriveSavers was able to extract data from the memory chip successfully. Despite some challenges related to NAND flash storage corruption, the team managed to recover over 18GB of data from the damaged flash drive.

The recovered data included photos from Barbara’s vacations, family gatherings, and personal moments. It also included scanned images of older photographs dating back several decades.

The data was returned to Barbara on a new, fully functional flash drive. The files were organized by type and date, making it easy for Barbara to locate her treasured memories.
