How to remove write protected error from a USB pen drive or memory card?


 
Sometimes we get an error when we try to copy or write some data on a USB Drive or a memory card. This is because the pen drive may be write protected. Many reasons can cause this problem and hence many solutions. 


Solutions :


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.


After the low level format, you may need to “Partition the drive“. Dont worry, partitioning a pen drive meansallocating it its File System and Cluster Size that was lost after the Low Level Format


For that :
  • Run diskmgmt.msc in Run (win +r).
  • In the disk management window, select the pen drive, right click on it and click on Format.


  • Now choose the File System and Allocation Unit Size and do not check the boxes below.
  • Click OK and the drive will be reusable after this.
4. It may have been deliberately write protected by the earlier post How to write protect your pen drive. So follow the steps to step 5 in this post and change the value to 0 and its done.

[Note : If none of the methods listed above solves your problem then your pen drive might have gone corrupted, so just get it replaced]

  1. ADMIN: TRY THIS IS ONE ALSO

    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\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
