"The Disk is write protected" how to fix this PC error., remove write protection for USB

Have you ever encountered this problem in your USB Drives or memory card?. When you try to open your files your computer just show this error message:

"The disk is write-protected. Remove the write-protection or use another drive."

Here are five options you can try:

1. Look for any Lock Switches.
Some USB drives and Memory cards have a switch that allows you to lock drive and prevent any changes. Examine the USB drive or Memory card closely. If you can find the switch, switch it to the other side to turn the protection off.

2. Check Permissions
a) Right-click on external hard drive and select properties in the explorer windows.
b) In the properties window, select the security tab.
c) Select the ‘user’ under user name and click on ‘Edit’.
d) Check if you have Write permissions. If you don’t, check the option “Full” for full permissions or “Write” for write permissions.

3. Modify a registry key StorageDevicePolicies. 
1. Open Start Menu ,
2. Run, type regedit and press Enter, this will open the registry editor.
3. Navigate to the following path:


If you can’t find the key StorageDevicePolicies , go to step 7.
4. Double click the key WriteProtect in the right pane and set the value to 0 In the Value Data Box and press OK button
5. Exit Registry
6. Reboot your pc.

If you can’t find the key StorageDevicePolicies in step (3) you have to create it manually.

7. Right-click HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\ and select New -> Key.
8. Enter the name StorageDevicePolicies.
9. Click on the new registry key StorageDevicePolicies and on the right pan right-click, select New > DWORD and give it the name WriteProtect.
10. Double click on it and set its value to 0.

4. Using Diskpart 
1. Start > Run -> type CMD and press enter
2. type diskpart > enter
3. type list disk  > enter
4. type select disk # (# is the number of the USB HDD you’ve plugged in )
5. type attributes disk clear readonly

5. Format your USB drive (last option)

F must  be the letter of your USB Disk

B. For Windows 7 Users only. If still the usb drive is write protected then you can execute a “low-level format” on the drive. Download the free software to perform the “low-level format” of your USB drive.

Important: After completing the low-level-format you may have to create a partition in that disk drive.
