How to repair the U disk

  
U disk that can not be opened as a mobile storage device connected to the computer through the USB interface, which has a small and portable shape and huge storage capacity. However, after using it for a long time, various problems will occur. Sometimes there will be no U disk drive. How to fix the U disk that cannot be opened? In layman's terms, USB is one of the types of interfaces that peripheral devices connect to a host computer. The plug-and-play feature means that the USB can be plugged into the computer at any time regardless of the state of the computer at this time. If you want to remove the device, you can safely remove the device from the computer according to the specifications. Removed. Frequent conversion to each computer, even a very secure U disk, will still produce a lot of problems, the more common U disk failure is the U disk can not open. The U disk cannot be opened. As far as the U disk itself is concerned, it may be that the crystal oscillator of the vulnerable component in the U disk is damaged due to severe vibration, and cannot be opened due to the vibration. On the other hand, it may also be because the frequent access to different computers, the U disk is damaged by computer virus software. In general, the reason why the U disk can not be opened is multi-faceted, and only one try to solve the problem. If you can find the root cause of the problem, it will be much easier to solve. Next, I will give you a few tricks to solve the U disk can not open, I hope to help everyone. Method /Step 1. The most direct cause of the U disk being unable to open is the file system corruption. A common method for this is to repair the disk. Right-click on "Removable Disk" and select “Properties> from the pop-up context menu. 2. Then in the window that opens, switch to the "Tools" tab, click the "Check the error to start check" button, select both items in the pop-up window, and finally click the "Start" button to check And fix the disk error. After the repair is complete, you can try to open the USB flash drive! 3. When the above method cannot open the USB flash drive, it is recommended to format the USB flash drive. Right-click on "Removable Disk" in the right-click menu that pops up and select the <;Format” item. In the "Format" window that opens, uncheck "Quick Format" and click the "Start” button. 4. After the above operations, if the USB flash drive still cannot be opened normally, try to swap the USB flash drive into a USB interface. Also make sure that the computer mobile storage related settings option is not disabled. Specific view and setup method: Open the “Run” dialog box and enter the command “gpedit.msc” to enter the Group Policy Manager. 5. In the Group Policy Manager window, click “Manage Modules”→“Systems”→“Removable Storage Access", ensure that the right side "Removable Disk: Deny Read Access" ; and <;All removable disks: Deny read permissions"; both are set to “not configured” or “disabled”. If not, double-click the corresponding item, and tick the “disabled” item in the pop-up window and click “OK” 6. After the above method still can not open the U disk, you can only use the U disk mass production tool for repair operations. This is also the most effective way to solve the U disk failure. Production tool repair U disk method U disk master model acquisition: Because the different types of U disk corresponding to the mass production tools are not the same, so if you want to use the mass production tools, you must obtain the U disk master chip model , ie PID and VID models. Search and download the “chipgenius chip detection tool” on the Internet. After the download is complete, double-click to install. Run “ U disk chip detection tool & rdquo;, then insert the U disk, the program will automatically identify and list the detailed hardware parameter information of the U disk. This includes the device's PID and VID as well as the master model. Search for related mass production tools on the Internet based on the PID, VID and master model of the USB flash drive. Of course, we can also directly click on the corresponding official homepage recommended below the detection tool to find and download the corresponding production tools. (Small Tips: Be sure to download the mass production tool that matches the U disk model. If it does not recognize or error, it is recommended to try to download other versions of the mass production tool. Just like the small series encountered, the latest official The version of the mass production tool, but the emergence of "read device error" tips, the final Xiaobian use "ACLOR Anguo AU6980 program mass production tools V2[1].12” this version of the mass production tool was successfully repaired). After the download is complete, go to the catalog of production tools, view the corresponding configuration files (such as the “AlcorMP.ini” file in this experience), and ensure that “PID” and “VID” information and U disk chip detection tools The displayed data is consistent. If it is inconsistent, it is recommended to modify the configuration file). (Tips: Of course, this step is not necessary, only if the equivalent production tool can't recognize the U disk normally.) Then run the corresponding mass production tool, then insert the U disk to be repaired, and the program will detect it. After the U disk, you can perform related operations. Click the “Start” button to perform the mass production process. After the U disk mass production operation is completed, the U disk will be revived. This article comes from [website] www.xxx
