"My USB flash drive got write-protected while I was copying a 3GB folder, and the write protection prevented the copy process. It happens every time I plug in the USB for about 5-6 minutes, then the write protection reappears. I don't know how it got enabled, but when I tried to copy a 9GB folder, the issue occurred again. I can't disable the write protection, nor can I format the USB flash drive because it always shows an error saying 'The disk is write-protected.' Is there any effective way to remove the write protection and format the USB flash drive?"
If you don't delve into their differences, flash drives and USB flash drives are often used interchangeably. Nowadays, portable storage devices like flash drives and USB drives play a significant role in managing data flexibly in our digital lives, such as transferring files between computers, backing up data, creating a Windows To Go portable USB drive, installing apps, and more. Generally, a branded USB flash drive should last at least five years with proper use. Though various issues with flash drives occur, most can be fixed on your own.

How to Format a Flash Drive After Removing Write Protection
Write protection refers to the ability of a hardware device or software program to prevent new information from being written to it, while also blocking alterations or changes to existing data. In simple terms, when a disk is set to be write-protected, you cannot normally write data to it or copy data onto it.
Write protection is usually accompanied by a Windows prompt on your PC, warning you that the disk is write-protected and giving some additional information.

Aside from write protection issues, you might also encounter similar “read-only” errors. If that's the case, don't panic – the write protection solutions below should also help you get rid of the read-only error.
Write protection on most USB flash drives, thumb drives, and SD cards is caused by either a physical lock or a change in a virtual attribute. Understanding the cause will help you resolve the issue and successfully remove the write protection.
Do you see a slide switch on the side of your flash drive? This is used to control the read/write permissions for the device. Most modern flash drives have one, and you'll find them on popular brands like SanDisk, Sony, and Kingston. You'll need to slide the switch from the “Locked” position to the “Unlocked” position. This will allow you to freely use your drive again without encountering the “disk is write protected” error.
With the help of Partition Manager tool, you can easily get rid of write protection with simple clicks. Here's how:
Step 2. Select your read-only USB, external hard drive, or SD card and click “Disable.”
Go to "My Computer" or "This PC". Under "Portable Devices", find your USB drive. Right-click on it, then select "Properties". In the pop-up window, click "Edit". Sometimes, there will be an option to remove the write protection. Change the status of this option and try again.
Currently, using the Windows Command Prompt is the go-to method to try and remove write protection from any drive in Windows 10/8/7. If you're willing to try out a slightly advanced command, you have a very high chance of successfully removing over 90% of write protections from a flash drive.
Step 1: Search for Command Prompt on Windows and run the program as an administrator.
Step 2. Type each of the following lines at the Windows command prompt, pressing Enter after each one:
Step 3: Once the disk has been unmounted, you'll see a message that says "Disk attributes cleared successfully." Type exit to close the window.
The Windows Registry Editor (Regedit) is a graphical tool in the Windows operating system that allows authorized users to view and make changes to the Windows Registry. While this is a last resort, it is not recommended as it poses risks and dangers when you attempt to remove the write protection.

Step 3: Click on "HKEY_LOCAL_MACHINE" to expand "System."

Note: If you don't see a key named “Storage Device Policies,” you'll need to create it: right-click “Control,” create a new key and name it “Storage Device Policies” >> right-click this new key, choose “DWORD (32-bit) Value,” and name it “write protect” >> finally, double-click it to change its value.
Don't attempt to format a write-protected USB flash drive until you find a way to remove the write protection. When the USB drive is write-protected, you can't use either Windows' built-in disk formatting tool or any third-party USB formatting tools to format it.
Fortunately, there are write protection removal solutions available for various storage devices. With the write protection removed from your USB drive, you can now format it smoothly. I recommend using the Free Partition Manager tool called Partition Master, which lets users format USB drives to FAT32, NTFS, or EXT. We suggest this instead of the built-in Windows formatting option because it offers additional features such as:
Step 1: Select the USB drive you want to format.
Plug your USB drive or flash drive into your computer. Download and open a disk partition tool. Right-click the USB drive that you want to format, then select “Format.”
Step 2. Choose the USB drive letter and file system.
指定新的 partition label, file system (NTFS/FAT32/EXT2/EXT3/EXT4/exFAT), and cluster size for the selected partition, then click OK.
Step 3: Check the “Yes” box to confirm the formatting of your USB.
If a warning message appears, click Yes. Back up any important data beforehand, just in case.
Step 4: Apply the changes.
First, click the "Execute 1 Task(s)" button, then click "Format" to format the USB drive.
