Data Recovery Tool

Visual NAND Reconstructor
Model: DER-VNR Chip-off data recovery and digital forensic tool for broken NAND storages such as USB, SSD, SD card, tablet, smartphone etc., with a user-friendly software interface. Special Features: • Extract data from damaged NAND flash storage devices
• Strong chip type support with constant updates
• User-friendly and flexible software

Description

Visual NAND Reconstructor is a powerful and user-friendly tool for chip-off data recovery and digital forensic projects on broken NAND flash storage devices. It has a universal NAND Reader that can read memory of any NAND package.

The NAND reader reads a physical image (dump) out of a flash memory chip via a special adapter, then the software processes the physical image and convert it to a logical image with file system.
