How to remove write protected error from a USB pen drive

1.  First of all try to locate a small switch (if any, that you may have not noticed) at some place on the drive or memory card reader. This is the prime reason for this error. If there is one, switch it to the other side to turn the protection off.

2. The problem can also be caused by some virus activity so just get it scanned by some updated good antivirus which may solve your problem.

3. Download HDD Low Level Format Tool 4.25 and run it to execute a “low-level format”on the drive. This may take few attempts to actually remove the error.

1. Open Start Menu >> Run, type regedit and press Enter, this will open the registry editor.

2. Navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentContr…

Note: If the registry key StorageDevicePolicies key does not exist, you will need to create it

Download this batch file called add.bat from here, and double click after download the key will be automatically added to registry.

3. Double click the key WriteProtect in the right pane and set the value to 0 in the Value Data Box and press OK button 

4. Exit Registry, restart your computer and then again re-connect your USB pen drive on your computer. That is it, done.

If the above method does not work for you, follow the below steps:

1. Copy all the important data from this drive to your computer because this method will format the drive and erase all the data on the pen drive.

2. Now download the Apacer Formatting Utility, Unzip this utility to a folder on your hard disk, preferably on a folder on desktop screen for easy access (Do Not Try To Save it on pen drive). Keep your pen drive plugged in, and double click on the Start.bat file in the folder where you unzipped the above utility. This will start formatting your pen drive, wait till the formatting completes and the LED on your pen drive stops blinking. Remove your pen drive after than and plug it in again.

The above two steps will solve the problem. If you still face the problem, follow the below steps:

1. Goto Start > Run, type cmd and press enter, this will open command prompt.

2. Type the following command on the command prompt replacing X with the drive letter of your pen drive.

CHKDSK X: /F

The above two methods will help you fix the problem.

Note: For all those who are out of luck in fixing the problem with their portable drives, I would suggest you to get your drives checked or replaced by the manufacturer to fix it for you
