The U disk doesn't read on the computer. The dot property shows that memory is 0, and the U disk cannot be opened, indicating the I/O device error. Formatting is also not possible.
Is there any physical damage to your U disk, such as collision, water entry, and severe vibration?. The data is likely to lose, but you can find some related chip production tools on the Internet, see if you can......
I've seen it.. It can be turned on on other machines. Format may be normal. U disk home kit V1.4 download the software inside a grid tool, if it is not the price may be bad!.. Next production tool for the same slice.. See if you can do it well... It can't be produced, that's really bad
There are two possibilities, one is the existence of bad sectors, two memory chip is damaged. If the data is important, taboo continuous power attempts, not to arbitrarily sweep the partition through the software. If it is a chip fault, even if only a limited attempt to electrify, it may cause more serious damage. If the data is not important, you can try to format; if the data is important, it is recommended through the authority of the 51Recovery data recovery. In short, because of the current production process problems, U disk and memory cards are more fragile than the hard disk, this situation should be careful operation.
It is very likely your USB were burned.
