A friend encountered a USB flash drive and suddenly the computer did not recognize it, and the drive letter was not displayed directly. When the USB flash drive was inserted into the computer, nothing happened. He was so heartbroken that he did not know what to do. In fact, you should pay attention to two situations at this time. One is whether you insert the USB flash drive to the computer whether there is a prompt to find new hardware, or whether the computer has a Ding Dong sound prompt to insert the device, if it does, it means that your USB flash drive is still saved, if not, you have to rule out whether it is you If you have a computer problem, try another computer. If it is still the same, it is more difficult to short-circuit the USB flash drive.
Let’s take the USB flash drive plugged into the computer and there is still response but no display as an example to talk about a simple solution. Of course, there is still a chance of success. Good luck:
Method 1: Right-click “Computer” and select “Management” from the pop-up menu.
In the opened “Computer Management” window, expand the “Storage” -> “Disk Management” item.
Right-click the USB drive letter that cannot be displayed normally, and select “Change Drive and Path”.
Then assign an unoccupied drive letter to the current U disk.
Method 2: We can also modify the registry to display the U disk drive letter.
Open the “Run” dialog box and enter “regedit” to enter the registry program.
Expand “HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer” in turn and delete the “Nodrives” key value.
Method 3: There is a very simple way to realize it, which is to use “USB monitoring software” to bring the U disk drive back to life. Friends who need it can click here to get the download of ” USB Monitor “.
1. Run the software and check the “Disable USB storage device” item.
2. Then check the “Enable USB storage device” item again to display the USB drive letter.
Method 4: If none of the above methods work, this is the most promising method, which is mass production repair method.
The general process is to first insert the U disk and then download chipgenius to detect what the U disk master control is. For example, chipgenius shows that the master control is Anguo
As shown in the picture above, it is controlled by Anguo AU6983 or AU6986, then go to the mass production tool catalog of this site to download the corresponding version of Anguo AU6983 and AU6986 mass production tools.
