Can't read and write on U disk? This method is worth a try

The most annoying thing about using a USB flash drive is "visible, not touchable". A locked USB flash drive is really a headache. Xiaobian here is a way to quickly get rid of this locked-in trouble.

First enter regedit in the start menu to enter the registry editor.

Locate the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Storage" key and see if there is any StorageDevicePolicies subkey.

If not, right-click on the Storage item and select "New-Item", and change the name to "StorageDevicePolicies". Be careful not to right-click in the blank space on the right.

Next, right-click in the blank space on the right side of the newly created StorageDevicePolicies subkey, select "New—DWORD (32-bit) Value", and name it "WriteProtect".

Double-click this WriteProtect, and modify the "Value Data" to 0 in the pop-up dialog box.

At this time, restart the computer, and then insert the U disk, the write protection should be broken. If it still doesn't work, the last feasible way is to perform mass production repair and completely reset the USB flash drive, but the price of this is that the data on the USB flash drive cannot be retrieved.
