Win7 does not recognize the USB disk (the USB disk cannot be Casino free 100 no depositrecognized,Win7 device driver failure) With the wide application of USB disks, many people have such a problem: in the Win7 system, it cannot be recognized after inserting the USB disk, prompting "device driver failure". How to solve this situation? First of all, we need to know some basic knowledge of USB flash drive and Win7 system. The working principle of the USB flash drive is to use the USB interface for data transmission. In the Win7 system, each device has a corresponding device driver, which can enable the device to communicate with the computer. Once the USB flash drive cannot be recognized, it is very likely that the Win7 system cannot correctly recognize the device driver required for the USB flash drive. Well, next, we will propose some solutions to this problem. Scheme 1: USB disk partitioning In many cases, the partitioning of the USB disk will affect the recognition of the Win7 system.If the USB disk does not have a partition, or the partition is not compatible with the Win7 system, it will be unrecognizable. We can use some USB disk partitioning tools to partition the USB disk, and then insert it into the Win7 system to try. Scheme 2: Update the system driver. As mentioned above, the USB disk cannot be recognized by the system. It is very likely that the Win7 system driver cannot correctly identify the device driver required by the USB disk. In this case, we can try to get the updated system driver. First, you need to find the device manager, select the drive of the USB flash drive, then right-click "Update Driver" and select "Search for Updated Driver". If there is a newer driver available, the system will install it automatically. Scheme 3: Replace the USB disk. If the USB disk has not been recognized, there may be a problem with the USB disk itself.In this case, we can try to replace a USB flash drive to solve the problem. However, it is recommended to back up the data in the USB flash drive before replacing it. Scheme 4: Use other devices. If the above methods cannot solve the problem, you can also try to use USB flash drives on other devices, such as WinXP system, MacOS system or other computers. If other devices can recognize the USB flash drive normally, then the problem is likely to be an error in the Win7 system driver, which requires more advanced methods to solve the problem. In summary, when the USB flash drive cannot be recognized, it is best not to throw it away or give it up in a hurry. You can use the above methods to try to solve the problem. If none of the above methods can solve the problem, it is recommended to consult professional IT technicians. I hope this article can be helpful to everyone.
