Method 3. Format Write Protected USB or SD Card in Two Ways

Formatting could be the last resort in order to make write-protected USB drive work again, but this will wipe out all data within it. If you just want to reclaim the storage, you may give it a try. However, write protection will come back if you format a USB stick in normal way. To avoid it, you need to format write-protected USB or SD card in Windows safe mode or use special write protection removal software.

Option 1. Format in Windows Safe Mode

Once your Windows computer is booted in Safe mode, just connect your USB or SD to PC and format it in Windows Explorer: right click on the drive and choose Format… Once the formatting is done, just restart your computer in normal way and see if write protection is removed from your USB.

Option 2. Format with Write Protection Removal Software

If you think it difficult to format write-protected removable device in Safe mode, then you may try write protection removal software. There are many tools claiming that they can remove write protection, but apparently, not all such tools work for all people. Here we recommend two of them which are worth a try: HDD Low Level Format Tool and Disable or Enable Write Protection.

Write protection is actually very useful when you don’t want to alter or lose the files in your storage drive. Of course, a better way to make your data safe is making enough backups. In case your files have been lost due to accidents or forced formatting, you can still recover deleted files from Windows hard disk, USB flash drive, memory card and other storage devices.
