After the camera memory card is inserted into the computer, the display U disk needs to be formatted. You can't turn on the USB flash drive until write protection is turned on. What is the solution?

This problem generally has two aspects:

First, the write-protected physical switch itself can be turned on.

2. If it is protected by the system, you can cancel the write protection by modifying the registry. The specific operation steps are as follows:

1. Open the Run program in the Start menu, then enter the regedit command and confirm.

2. After entering the Registry Editor, select the key item "HKEY_LOCAL_MACHINE".

3. Then open HKEY _ Local _ Machine \ System \ Current Control Set in turn, and find the control items under the current control set.

4. Find out if there are any storage device policies below. If not, right-click the control and select Project in the New submenu. If there is, there is no need to build it.

5. Then, in the right window of StorageDevicePolicies, right-click the blank area and create a new DWORD value.

6. Name the newly created name "WriteProtect", right-click "WriteProtect" and select "Modify" to keep its value as "0". Then press "OK" to save and exit the editing DWORD window, restart the computer, and the write protection problem will be solved.

Before moving the registry, you must back up the registry, and you can use the backup to restore it after modifying the registry incorrectly.
