My USB flash drive is write protected. How to modify?

I'm dizzy with the password you set yourself?

USB flash drive write protection: Modify content but cannot be saved.

The USB flash drive is write-protected and cannot modify the file, which can be solved in the following ways:

1. Check if there is a write protection lock on the USB flash drive, and if so, just turn the slider to the other side to turn off the write protection.

2. If there is no write protection device on the surface of the U disk, it is caused by system settings, and you can use the tool plan to cancel: open the security guard-manual service, search for "the U disk cannot modify the file" to find the corresponding solution and fix it.

This is your own: use the mass production tool.

Here's what comes from the web:

I believe many people have encountered such a problem: a good USB flash drive, suddenly there is "The floppy disk cannot be written to the floppy disk because the floppy disk is write protected, please remove the write protection of the volume from the drive device harddisk dr7." "I can't read the data, let alone write it.

Looking online many times and not solving the problem? So some people say,Turn on the write protection switch (this is the funniest,I guess if you can find the person who can find the switch,I've tried it.,Won't go online to find this answer) or your USB flash drive is going to be repaired.,Or the USB flash drive is dying.。 Some people even said, it's over, your computer is probably poisoned, reinstall the system.

In short, there is no solution. Let me first talk about a few characteristics of this situation:

1. It cannot be read or written, let alone deleted the file, or it directly prompts "the file or directory is damaged and cannot be read".

2. It cannot be formatted, and the format directly prompts you: "U disk write protection, cannot be formatted" or "This disk has write protection".

3. And most importantly, the USB flash drive cannot be self-repaired, or it cannot be formatted directly with low-level software.

ps:Someone is proposing to go to the next low-level U disk software,Low grid,I think the person who said this is equal to the difficulty of everyone.,Let's not say that such software is good to find,Not to mention the Internet now,If you don't do it, you'll be poisoned.,That's what makes you even more bitter!

In mid-March 2010, I encountered such a thing, when I wanted to scrap the U disk of the heart, suddenly, I clicked on the computer disk management, and saw the U disk in it, which is easy to do, formatted, successful! I don't give up. Here's how:

Right-click "My Computer" - Management "- Disk Management", as long as you can see the drive letter of the U disk in it, OK, it means that your U disk is normal, right-click and select the file format to be formatted, select FAT32 (the default is FAT, but most of the U disks are FAT32), select "Default" for the allocation unit, click "OK" so it starts from 1%, you will be very excited to look at it until 100%, wait a while, you will see the words "good state", the format is completed. Accidentally, I thought that the problem that the computer could not solve, but it was easy to solve it in another way. Go ahead and format your USB flash drive!
