Protect usb drive from viruses

We all have faced usb drives infected with viruses and therefore damaged files where important things might have been lost.The good news is that we can do something to prevent these kinds of cases from happening to us.There are two methods that prevent a usb drive from getting infected.The first method is a to buy a usb drive that has a physical switch which makes it possible to activate write-protection.And what that does is it closes the system from writing or making changes to the files that are contained in the drive.And the second method is very similar but it is implemented in software means.Follow me step by step because I am going to demonstrate it.

Open “Run” either by typing Win Key + R keys or by going through the Start menu.

Once Run is opened then type in : diskpart

and then press Enter.

You will be presented with a black window which is the program whose name you typed in before ,Diskpart.

What this program ( Diskpart ) does is create partitions,modify partitions,delete partitions,change their attributes,etc.

So it this program which is going to make your usb drive write-protected.

Now we need to type a command that will show us the hard drives and usb flash drives that are present in the computer.And that command is : list disk

Type in the command and then press Enter.The result you will get will be similar to the window below.

We need to find the corresponding disk number for our flash drive.In my case I know that my usb drive is disk number 2 because I know that its capacity is 8GB ( or 7633 MB ) as is shown in the Size column in the image above.

Now that we know the disk number we need to type in another command that will select our flash drive in order to make it active for further operations.

NOW BE CAREFUL : You should see clearly which disk number your flash drive is because if you select the number of another drive like your currently operating hard disk it may result in problems.

Now type in the following command : select disk x

(where x is the disk number of flash drive ,yours may be 3 or 5 or whatever).

You will be greeted with a result as below.

 

Now that you have selected your usb drive you are ready type in the last command which will make your usb drive non-writable.Type in this command : attributes disk set readonly

 

 

 

 

Now you can go on and try to copy something into the usb drive and see if it will allow you to do so. Once you try that you will get an error like below :

How To Remove:

Now the question is how to remove the write-protection attribute so that you are allowed to copy files into the usb drive.

And the answer is this command : attributes disk clear readonly

Once you type in that command you will be freely allowed to copy anything into the usb drive.
