How to Fix Write Protected Error...

What is Write Protected error and why it happens?

In the Write Protected error, we can not write or copy any data in to flash/USB drives and even can not format it.
There are many reasons that causes this problem. Here I give share the solution to fix that problem.

Solutions: 

  • Just download this helpful software from here 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.
  • If that low level format tool does not work, try another one Link.
  • 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.
  • 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.

Solution 1 :

  • Run diskmgmt.msc in Run.
  • In the disk management window, select the pen drive, right click on it and click on Format.

Solution 2:

  • Follow the steps in this post and just put the value 0 (zero) in step 5.

Hope any of the methods listed above solves your problem.

How to make your USB as Write Protected

Today when I got some data transferred in my friends pen drive at my rum that made me think that I need to remove Write Protect his pen drive. The drive has about 7 different types of viruses in Pen Drive. It is so irritating to always scan the drive to remove the viruses that also consumes our important time. So I got something to share with you guys “How you can Write Protect your Pen Drive” or “How you can prevent your pen drive from getting infected”.

Things to note before doing this :

  • As the trick will write protect your pen drive, you will not be able to transfer anymore data until you disable it again (works best if you only wish to copy or read something from the drive).
  • If you are not good at editing registry then backup yours registry file.
  • You need Admin rights to work upon the Registry Editor.

Steps to make your drive Write Protected :

  1. Open Registry Editor by typing regedit in Run dialog.
  2. Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
  3. Find a sub key inside it named “StorageDevicePolicies”. If it does not exist there then we need to make it. Right click on “Control” key -> New -> Key. same it “StorageDevicePolicies” without quotes.
  4. Now right click on this newly created key and then click New -> DWORD value and name it as “WriteProtect”.
    5.  Modify this key and give its value as 1.

     6. Click on OK and restart your computer.

Now no more data can be transferred to the drive but to start using the drive again just give the "WriteProtect" key a value of 0 instead of 1 and don't forget to restart the PC.
