How to return the expansion disk to the prototype

First, to detect a U disk chip. Chip genius! with tools

Device name: [F:]usb Mass Storage Device (USB2.0 Flash Disk USB Device)

PnP Device Id:vid = 1221 PID = 3234

Device Serial Number: 1000000000000e7e

Second, through the discovery of the Internet, we need to restore the actual capacity of the U disk by means of the production tool corresponding to the chip.

Summary: Check and repair the fake u disk, expansion u disk, only a few steps on it.

1, with Mydisktest Check whether the expansion of the U disk.

2, with Chip genius check U disk chip.

3, to find the chip corresponding to the mass production tools, production to restore the actual capacity.
