What's Pen Drive Write Protection?
Write protection is defined as the ability of a hardware device or software program to prevent new information being written, meanwhile old information being modified or changed. In simple words, when a disk is write-protected, you cannot use it normally to write data or copy data on it.
Write protection usually appears on Windows PC with a Windows prompt message, warning you that the disk is write-protected with some supplementary messages.

Other than the write-protected problem, sometimes we would encounter the other similar "read-only" error. If it happens to be your case, don't panic, the coming up write protection removal solutions can help you remove the read only error as well.
Chances are that 99% write protection on a USB flash drive, pen drive and SD card comes from the physical lock and virtual attribute change. By figuring out the behind reasons, it becomes easier for us to cure this problem and remove write protection successfully.
Method 1. Check Lock Switch and Disable Write Protection
Did you see a lock switch on either side of your pen drive? The lock switch, as the picture presents, is designed to control the ability of to read and write on the device. Most modern pen drives are designed with such lock switches, which we've seen on SanDisk, Sony, Kingston, and so many popular brands. You must toggle the switch to the position of "unlock" from "lock". By doing this way, you'll be able to use your pen drive freely again, without meeting the 'disk is write-protected' error again.
Method 2. Change Pen Drive Read-Write Properties
Go to My Computer/This PC and under Devices with Removable Storage, look for your pen drive device. Right-click on it and click Properties. Click Edit, in the pop-up box, sometimes there's an option to Remove write-protection. Change the status of this option and try again.
Method 3. Disable Write Protection Using CMD
Thus far Windows Command Prompt is the must attempt method to remove write protection from any drive in Windows 10/8/7. If you are willing to challenge the command that seems to be a little higher-leveled, it's very likely that you can successfully remove over 90% write protection from a pen drive.
Step 1. Search command prompt in Windows and run the program as an administrator.
Step 2. On the Windows Command Prompt, type each command line as follows and each command should be followed by an Enter key.
- list disk
- select disk #
- attributes disk clear readonly
Step 3. When the write protection has been removed, you'll see the message 'Disk attribute cleared successfully'. Type exit, so you can close the window.
Method 4. Remove Write Protection with Write Protection Removal Software
If you don't consider yourself a pro-computer user and you're not familiar with command-lines, don't worry. There are graphical-based solutions to help you remove write-protection from your hard drives, USB drives, and even SD cards.

Method 5. Remove Write Protection from Pen Drive Using Regedit.exe
The Windows Registry Editor (Regedit) is a graphical tool in the Windows operating system that allows authorized users to view the Windows registry and make changes. Though it comes as the last resort, this Registry editing way is not so recommended as it exposes risk and danger at the same time when you try to remove the write protection.
- 1. Only advanced users should work with the Windows Registry Editor and administrators should always create a backup of the registry before making changes.
- 2. Editing Windows Registry indeed helps remove write protection from your pen drive. However, we found that it's usually effective on earlier Windows operating systems, including Windows XP and Windows Vista. If you're Windows 7/8/10 users, it hardly works for you.
Step 1. Connect your pen drive to your computer.
Step 2. Press Windows + R keys and bring up the Run box. Type "regedit" in the empty box and hit Enter.
Step 3. Hit "HKEY_LOCAL_MACHINE" to expand "System".
Step 4. Find the "Current Control Set" in the "System" list to click "Control".
Step 5. Check whether there is a key named "Storage Device Policies" to change the digit in the "DWORD value" box into "0" and press "OK" to save the change.
Note: if you cannot find the key named "Storage Device Policies", you are supposed to create one: right-click "Control" to create a new key and name it as "Storage Device Policies"=> right-click this new key to open "DWORD Value" and name it as "write protect"=> Double click it to change the number.
