Generally speaking, it is caused by insufficient power supply of USB interface.
There are not many ways to solve this problem, so we can only try to change other USB ports or plug them in several times, or try to restart with a U disk.
Plug in the mobile hard disk and keep calling it Didi, otherwise you will be prompted to format the disk.
1, change a data cable to improve the power supply of the mobile hard disk, for example, change a dual USB head to access the data cable.
2. If it is used in a notebook computer, it may be caused by insufficient power supply of the U port of the notebook itself, which cannot be solved.
3. Excluding the above, there are also defects in the design or material of the mobile hard disk adapter card. This question can only be changed to mobile hard disk box.
4. Open the device manager to see if the USB mass storage device driver is missing. If so, download the driver wizard. After installation,
If you run it online, it will automatically detect all your device drivers first, and then download and install all the device drivers it suggests you install. If not, change it again.
Enter the driver fine-tuning option, download and install the recommended updated driver there, and restart the computer to see if it is ok.
5. You need to kill the U disk virus (it is recommended to download a USBCleaner). If not, use the format provided by the system. If it still doesn't work, use ChipGenus or ChipEasy to check your USB flash drive chip model, then download the production tools corresponding to the USB flash drive chip model and the tutorials corresponding to the production tools, and reformat your USB flash drive for mass production.
The above situation and solutions are for your reference. If you find it helpful, please adopt it in time.
