How to write protect or unwrite protect your USB
Note: You have to open your Command promt (CMD) as an administrator
Step 1: First insert the USB Flash Drive and open the Command Prompt in Admin mode. Don’t know how to do that, then you need to visit this here. Open an Elevated Command Prompt or Open cmd as Admin
Step 2: Now type DISKPART and press enter.
Step 3: Type LIST DISK and see the name of your USB Drive. Now Type SELECT DISK 1 (name of the drive.)
Step 4: Now type ATTRIBUTES DISK to see the current state and permissions of the drive.
Step 5: Now to enable write protection on USB Flash Drive, just type ATTRIBUTES DISK SET READONLY and press enter. Now try adding some files to the USB drive and you can see that a message pops out saying that the disk is write protected and read-only.
Step 6: If you want to remove or disable the write protection on USB Flash Drive, just type ATTRIBUTES DISK CLEAR READONLY and press enter. Now again try adding some files and you can see everything is normal as before.
