What should I do if the disk is write protected? Several ways to remove the disk from write protection

Disks, mobile hard disks, USB flash drives, and SD cards and TF cards (also known as mobile phone memory cards) can be written to with write protection. The specific performance is that files cannot be saved and files cannot be deleted. The following system home Xiaobian introduces several ways to remove the disk write protection. Many U-disks, SD cards, and ferrules have a slider that we can use to write-protect and remove write-protection settings. As shown in the following figure: What about the U disk, SD or FT card (memory card) without the write protection function and the prompt disk that has the protection function but the slider does not work? There are three solutions to this phenomenon: 1. Using the error correction command we can use the Windows system disk detection and repair commands to try to solve this problem. Please follow the prompts: - Open the run (shortcut Win+R) → enter “CMD”→ enter the run window after the carriage return (black window) - enter “k:” (colon is essential, K stands for The write-protected disk drive letter is changed by your own actual situation) - then enter: CHKDSK /F Enter. Note: This method does not work if your system is set to write protection for removable disks (in the registry, as explained below). The system will prompt: The current drive cannot be locked, and Windows cannot perform a disk check because the volume is set to write-protected. 2. Modify the registry As mentioned above, if you use the system's CHKDSK /F error correction command, the system displays: "The volume has been set to write protection". Then it is very likely that your operating system registry has been added the "StorageDevicePolicies" item. We can remove the write protection by simply deleting it or modifying it. The method steps are as follows: - Open the run (shortcut Win+R) → enter regedit and press Enter - find this directory: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\StorageDevicePolicies- After clicking StorageDevicePolicies, you will see a window in the right column WriteProtect- Right click on WriteProtect → modify (M) & rarr; pop up the following window Note: If you do not see StorageDevicePolicies then this method does not apply to you (but you can try to create StorageDevicePolicies and WriteProtect, but basically hope 渺茫).
