U disk common problem 1: When the drive letter is detected, it prompts that the disk is not formatted. Do you want to format it? The disk has 0 bytes and the disk cannot be opened.

In the process of using a USB flash drive, we often encounter the problem that the USB flash drive cannot be formatted and the properties of the USB flash drive are displayed as 0 bytes. After inserting the U disk and double-clicking it to open the U disk, a prompt window "Your disk has not been formatted, do you want to format it?" will pop up. When you click OK to format, you are prompted again with "Windows cannot complete the format." When we right-click the U disk and view "Properties", you will find that both the available space and the used space show 0 bytes, as shown in the following three pictures:

Reason analysis:

This situation occurs, on the one hand, due to the quality of the U disk itself, and on the other hand, it is caused by our improper operation. So how do we solve the problem that the U disk cannot be formatted and the U disk properties show 0 bytes?

Solution:

Step 1: Right-click the USB flash drive and "Properties" - "Tools" - "Start Check" - "Automatic Repair and Recovery". The success rate of this method is very low. If there is no response, continue to the next step.

Step 2: Search "Usboot tool" on Baidu to find and download the Usboot tool. After running the Usboot tool, forcefully format the U disk in "HDD mode". We follow the instructions of the software to unplug and insert the U disk. Although the U disk is forcibly formatted using this method, some U disks may still display 0 bytes and still cannot open the U disk. This step can only fix some U disks. If If we still can't get it done, we can continue to the next step!

Step 3: If you think "Step 1" and "Step 2" are troublesome, then you can directly perform the operation of the third step. We disassemble the USB flash drive, check the model of the USB flash drive chip, and then we search on Baidu Searching for mass production tools of this model will solve the problem!

The above three steps can solve the problem that most U disk properties show 0 bytes and cannot be formatted. If it still cannot be solved, it is probably that the Flash chip of your USB flash drive is broken. The USB flash drive is scrapped, buy another USB flash drive!
