USB Device ID: VID = 058F PID = 6387 Device Vendor: Alcor Micro Device Name: Mass Storage Device Device Revision: 0102
Before attempting raw data extraction from a highly unstable drive, identifying the controller chip helps specialists determine the correct pinout configurations. Safety and Best Practices
It detects the flash memory chip brand (like Samsung, Toshiba, SanDisk, or Hynix) along with the Flash ID (FID). This is crucial for matching the memory type with compatible repair firmware. 3. USB Protocol Detection
Because when it comes to USB hardware, what you do not know really can hurt your data. ChipGenius helps you make sure you always know exactly what is plugged into your machine. Chipgenius V4.21
Click on the device you want to inspect. The lower pane of the interface will populate with detailed detection results. Key sections to examine include:
Note for fake drives: The MPTool will automatically detect the true boundary of the flash chip and restore the drive to its real capacity (e.g., fixing a fake 1TB drive back into a stable, usable 16GB drive). Safety and Best Practices
| Tool | Best Use Case | Key Difference | | :--- | :--- | :--- | | | When ChipGenius gives an “unknown” result | ChipEasy has a live online database , so it can identify some newer controllers that are not yet in ChipGenius’s local database. | | Flash Drive Information Extractor (usbflashinfo) | Cross‑verifying suspicious results | Many advanced users recommend running both ChipGenius and usbflashinfo together, as each sometimes picks up details the other misses. | | MyDiskTest | Detecting fake capacity (expansion) drives | ChipGenius tells you what the hardware is; MyDiskTest writes and verifies data to confirm if the claimed capacity is real. | | Check Flash | Long‑term stability testing of flash media | This is more of a low‑level sector tester for read/write verification and bad block detection. | USB Device ID: VID = 058F PID =

ChipGenius is a portable application, meaning it requires no installation. Follow these steps to diagnose your device:
: Optimized reporting of mismatched capacities, a crucial feature for identifying fraudulent storage drives. Technical Data Extracted by ChipGenius
Helps identify "fake" flash drives by reporting the actual storage capacity of the internal chip versus the advertised capacity.
ChipGenius was developed by the Chinese community (notably users like from the USBDev.ru forum) to solve a common problem: USB flash drives and MP3 players that don't match their advertised specs. While Windows sees a "USB Mass Storage Device," ChipGenius looks deeper at the actual "brain" (the controller) and the "memory" (the flash chip). The Evolution: V4.21.0701
ChipGenius v4.21 is a ubiquitous, lightweight, and portable utility designed to identify the internal components of USB devices. It is an essential tool for technicians, hardware enthusiasts, and data recovery specialists.
