How to protect a USB drive from writing

So, many times we need to write protection for our USB flash drive to protect it from viruses and other malware. Since flash drives are so popular and most widely used to move data between computers, they are the main target for attackers as a means of infecting computers in the world of computers. In addition, because a USB flash drive is not a permanent storage device (ROM), data inside it can be easily modified or deleted by malicious programs.

But unfortunately, most new flash drives don’t have write protection features as manufacturers want to reduce their production costs. Therefore, the only way to protect your USB flash drives is to enable this feature on your own computer.



Steps for Write-Out-Protect Your USB Drive:

This can be done by adding a small entry to the Windows Registry that acts as a switch that can be enabled to use Write Protection or disabled to allow write access. There you go:

Open the Registry Editor (open the Run dialog box, type regedit and press “Enter”).

Go to the following registry key:.



HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \

Create a new key named StorageDevicePolicies . To do this, right-click on the ” Control” element. , click “Create” again -> ” Key” and name it ” StorageDevicePolicies” .

Now right-click on StorageDevicePolicies and create value New -> DWORD (32-bit) and call it WriteProtect .

/></p><p>.<br/>Double-click on WriteProtect and set the Value data to 1 .</p><p>Now the legal protection of USB flash drives is enabled on your computer (no need to reboot), so that no one or any program can add / remove content from the USB flash drive. Any attempt to copy or upload files to the USB Flash Drive will result in the following error message being displayed.</p><p>To restore and remove write protection, all you have to do is simply change the Value for WriteProtect from 1 to 0. Now all USB devices are rewritten.</p><p>Companies choose which security policies to install: some fight to prevent third party software (games, etc.) some fight to prevent anything from being taken away (especially protected information). Sometimes thoughtlessly just prohibit all USB devices and users to exchange the necessary service information (when there is no shared LAN) have to be pretty exhausted acting within the policies (burn this to a CD and transfer through a network administrator’s computer which can read flash drives, etc.). In my opinion, if the main goal to prevent data leakage is to set the mode of working with flash drives readonly (for certain groups).</p><p>There are several products that allow you to set the mode of work with USB flash drives:</p><ul><li>DeviceLock <a href=www.devicelock.com

  • Lumension Device Control www.lumension.com (I like it very much)
  • GFILANguard www.gfi.com
  • All of them perfectly cope with their functions, know how to work centrally with AD. The main drawback is that it’s expensive.

    Sometimes it can be difficult to remember and perform the above steps every time you want to enable/disable write protection. Therefore, as an alternative, there are many tools to automatically enable / disable the write protection feature. One tool is USB Write Protect from Naresh Manadhar . With this tool, you can restrict write access to your USB drives at the click of a button.
