SOURCE: Remove Write Protection

This seems to be the problem of most of us these days and some of our readers who wanted to know the methods how they can remove the Write Protected error from their USB drives like Pen Drives and memory cards.


What is Write Protected error and why it happens?
In the Write Protected error, we can’t write or copy any data in our flash drives and even can’t format the drive.
There are many reasons that cause this problem, let’s see solutions of them.
Solutions:
• 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.
• Yes I know this problem is also occurring these days without this switch but not to worry. Just download this helpful software form here

http://www.softpedia.com/get/System/Hard-Disk-Utils/HDD-Low-Level-Format-Tool.shtml

and run it to execute a “low-level format” on the drive. This software is quite handy and may take few attempts to actually remove the error.
• The problem can also be caused by some virus activity so just get it scanned by some updated good anti virus which may solve your problem.
• BUT if none of the methods listed above solves your problem then your pen drive might have gone corrupted, so just get it replaced.
Hope any of the methods listed above solves your problem.
Update 1:
After the low level format, you may need to “Partition the drive“. Dont worry, partitioning a pen drive means allocating it its File System and Cluster Size that was lost after the Low Level Format.
For that:

1. Run diskmgmt.msc in Run.
2. In the disk management window, select the pen drive, right click on it and click on Format.
3. Now choose the File System and Allocation Unit Size and do not check the boxes below.

Write Protection on any portable USB Device can be applied by the physical lock provided on the card adjuster or some times provided on the pen drives, so make sure to make your drive not write protected by moving the lock in right direction.

But even after moving the physical lock for write protection the problem can happen due to some virus action. This happens when some virus or script which applies the registry hack to make any drive write protect when connected to the computer, In that case follow the procedure below to remove write protection from your pen drive.

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\CurrentControlSet\Control\StorageDevicePolicies

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.
