Today in the use of U disk when the problem occurs: Insert a U disk click, prompted the disc is not formatted, asked whether to format. Make sure you are formatting and remind Windows not to complete the format. Then right click on the U disk to select Properties, found that free space and used space are displayed 0 bytes. What is this series of questions? Let's take a look at how the master is solved.
There has been such a problem, on the one hand is due to the quality of U disk, on the other hand, the use of their own improper behavior caused by the process. So how do we solve this, to provide you with the following solutions.
The first step: right click on the U disk, in the Properties-"tool-" Start checking-"automatic repair and recovery." The success rate of this step is very low, basically does not have any reaction, the second step is implemented.
Step two: The next Usboot tool, after running in HDD mode on the U disk forced format. Here, press it to dial down and insert the U disk. Use this step although forced to format the U disk, but some U disk may still be 0 bytes, still can not open. This step can be a part of the most difficult to handle can be used in the third step.
Step three: If you think the first second step may be a problem, skip to step three. Open u disk, look at its chip model, and then in Baidu to find this model of mass production tools. I'm a Sony USB drive, the model on the chip is MW8209, so I searched up and down the MW8209 of the mass production tools, we carefully optimistic about the size and name, do not under what other tools to ha, this tool download is not installed, to install those must be false ha.
With these three steps most of the U disk appears 0 bytes can be resolved, if still not, that is your flash memory disk is broken. In other words, your USB drive has been scrapped, consider buying a new one.
