How to Lock USB Drive and Make it Read Only

USB drivers are considered as one of the sensitive ports of a computer. After the launch of USB portable drivers, they can be easily attacked by different viruses and malware woes, but only if you behave sketchily. A research claims that in the last two years, around 70 percent of the businesses have somehow lost their confidential data to USB flash memory sticks.

But you can avoid this mess to a large extent by locking write access to your USB drive and making it protective from any kind of autorun file. In this step by step guide, we have used Windows Registry Editor and a dedicate Windows tool to do this task.

Step 1: Using Windows Registry Editor

At first, you have to open Windows Run and type the command regedit. This will open Windows Registry Editor. The command will only run if you are a computer administrator.

Step 2:  When Windows Registry Editor opens, navigate toHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies. Most of the time the key StorageDevicePolicies is available by default, but if it’s not there, you will have to make a new one. To make it, you need to right-click on Control folder in the sidebar and click on the option New -> Key.

Step 3: Afterwards, open StorageDevicePolices and make a new DWord which can be found on the right-click context menu.
 

Step 4: Type WriteProtect under the Value name, and double click on it to adjust its value. Type 1 under the Value data and save the settings.

Step 5: All done. You can now edit any file on any removable device inserted in to your USB drive. You can also use a tool USB Write Protect for this purpose.
