Write protected usb is when you try to copy something and system won’t let you do it. You are trying to save data on your USB flash storage in your windows or linux operating system, but there’s a problem. Any attempt to save displays the message that the usb drive is write protected.
The drive won’t even allow you to reformat it, and there’s no apparent switch for enabling or disabling the hardware write protection. Confused? There are many ways using which you can remove write protection. From all the below mentioned steps, one of of them might work for you. If none of the steps work, chances are your flash drive has gone bad and now it is time to purchase a new one. So, here’s how to format write protected USB flash drive and start using it again.
1. USB Hardware Switch For Write Protection Removal
We’ll start with the simplest issue. Many USB flash drives feature a switch on the outside, usually on the sides, that you may use to turn on or off the write protection. If your USB drive has one, slide it off.
Change switch direction of your USB drive and check if you can format it this time. If that works, your problem is resolved, and all you need to do is ensure the usb hardware switch does not accidentally get moved in the locked or wrong position again. If there’s no switch (most common), or you still can’t write any data to the USB, you’ll need to employ other methods.
2. Remove USB Write Protection Using Diskpart CMD Tool
Before starting, insert your usb flash drive into your computer’s USB port.
Windows OS has a built-in command-line based disk partition management tool called Diskpart. You can open it by pressing Windows key + R, write cmd, then hitting Enter.
User Access Control will prompt you to confirm the action. Click Yes to continue.
You should now see CMD, the command-line tool. At the prompt, enter below commands:
A new command line window will show up with a new DISKPART prompt. It’s time to see which hard disks and flash drives are attached to your PC:
The resulting table will list the currently available storage devices. But how to identify your USB drive?
Disk 0 will be your computer’s main system drive. This is the one that Windows is installed on. If you have multiple partitions, these will be sequentially numbered. Note that the size is displayed for each partition.
With a USB flash device connected (which will be Disk 1 or higher), you should be able to identify it by its comparatively low storage capacity.
Therefore, Disk 2 is the USB flash drive. You should be able to check the capacity on the device itself, as this is usually printed on an usb drive’s casing. If not, you’ll be able to confirm it through Windows Explorer file manager.

Before going further, be certain that you have identified the right USB pen drive. Also, note that USB flash drives can be as high as 1TB in capacity at the time of writing, which could be larger than your computer’s HDD. Making the effort to be completely confident at this point is critical to the integrity of your computer’s data.
Once you are sure, it is time to select the disk. In our example, that means entering:
select disk 2
This will be confirmed with the message that Disk 1 is now the selected disk. Next, request attributes:
Many of different information will be displayed. Check the first line. This is the Current Read-only State of your flash drive. If you unable to write to the disk or reformat it, then Current Read-only State will be set to Yes.
Note that in our example, it is set to No as write protection is disabled on our usb flash drive!
But you can easily remove the write protection from your USB drive. Just type the below command:
attributes disk clear readonly
If successful, validation of the step will be displayed with the message “Disk attributes cleared successfully.”
You can now format the drive using Diskpart’s clean command. Again, first, ensure you select the right disk:
select disk 1
You can then create and format a partition:
create partition primary
Wait for this step to complete. After completion, you should now have a fully working and formatted USB flash drive.
Check the write-only status of the drive by copying a sample file.
3. Virus that Can Cause Write Protected USB Problem

4. Remove Write Protection Using Software
