What Caused Write Protection on USB

Sometimes, people add write protection to files on a storage device from being modified or erased. However, storage devices like USB flash drives, SD cards, and internal or external hard disks may become write-protected due to the following reasons:

  • The physical switch of the USB is on the Lockside.
  • USB is set as Read-Only by mistake.
  • BitLocker protection partition is turned on USB volume.
  • Third-party encryption software or virus caused by the disk is a write-protected error on USB.

The only way out is to remove write protection. Following the complete guide on this page will make your device viable for saving and transferring files again.

Method 1. Remove Write Protection with Physical Lock Switch

Sometimes, when the USB drive or the SD card physical switch is locked, the device becomes write-protected on all PCs and devices you connect. Let's see how to use the physical control to remove the protection from SD card/USB:

Step 1. Locate and turn the physical switch ON to OFF on your USB or SD card.

Step 2. Connect the unlocked USB or SD card to your computer. Check if the write-protected state disappears.

Method 2. Remove Write Protection from USB via Diskpart Command

This option clears the read-only attribute of your drive to make it writable. This works for your internal drives, external drives, USB drives, and even SD cards.

Let's find out how you can use the Diskpart command to fix the issue:

Step 1. Press Windows + R keys and type cmd in the box that opens. This will launch Command Prompt.

Step 2. Type diskpart in the Command Prompt window and press Enter.

Step 3. Type list disk and press Enter to view the available disks.

Step 4. Type select disk 2 and hit Enter. Replace 0 with the write-protected device number.
