Hi Lalitesh Soni

I would recommend you to connect the drive and run the Command Prompt. Type the following commands:
List Disk
Select Disk n (n must be the number of the drive)
Attributes disk clear readonly

Please check if the write protection is still activated. Make sure there is no small button on the pendrive, which enables the protection.

Hope this helps

Check the drive or card for a physical lock. Many USB drives and sd cards can have a physical lock switch that turns on write protection. Check to make positive that the drive doesn't have this lock enabled.
If your lock mechanism has been broken, see Fix a Broken Lock on SD Cards for a guide on fixing it.

Check if the drive is full. You may get a write protection error if there's no more space on the drive. You can see the quantity of free area on the drive by choosing it within the Computer/This laptop window. If your drive does have free area, the file you're trying to copy to that should still be overlarge.

Check the file's attributes. Sometimes the file that you are trying to copy is truly the one that is write-protected, not your USB drive. The error will be slightly totally different, but looks pretty similar. You can modification your file's attributes by doing the following:
Windows - Right-click the file and select "Properties." Uncheck the "Read-only" box and click "Apply."
Mac - Control-click the file and choose "Get information." Expand "Sharing & Permissions" and set the "Privilege" column to "Read & Write" for your user name.

Scan your USB drive or card for viruses. Whenever you plug a USB drive in, especially one that is been plugged into another laptop, you should scan it for viruses. Many virus scanners will be organized to scan USB drives automatically once they are connected, or you can right-click on the drive and choose "Scan with Antivirus."

Scan your computer for viruses and alternative malware if all drives are write protected. If every drive you insert in your laptop becomes write protected, you may have a pestilence or malware infection.[1]
Run an antivirus scan on your entire laptop using your antivirus program.
Download and run Malwarebytes Anti-Malware. You can transfer it for free from
See Remove Malware for a lot of careful virus removal directions.

Run UsbFix to scan your USB drives. This is a free, open-source program designed to find issues with USB drives and Windows USB drivers. You can download UsbFix without charge from
Click "Research" after launching UsbFix.
Click "Clean" after the scan has completed.
Test your USB drives again.
