Methods: In general, when you buy a U disk, you will have the low level formatting tool software of the U disk. But if it is a motley, it is necessary to go online to find the right tool software. My friend's u disk is a motley, the network introduced a lot of kinds of low grid tools, there are Mformat, Pointclip, Usbboot and U Disk Universal Format Tool Productiontool, their usage is very similar, but these several tools I tried did not fix, finally used a " Star Shuttle low-level format tool PDX8.EXE "and fix it." This tool is easy to find on the Internet, I would like to introduce the use of this tool software:

Select "Low level format" that is low-level formatting, in the figure selected U disk capacity, and finally click "RUN", low-level format, low speed is slower, the format is OK.
