How to protect a USB Flashdrive --- Lock a Pen Drive

Flash drives have become the storage medium of choice these days. With the increasing storage capacities available, people are beginning to store a majority of their data on pen drives. But in such cases, data security is a persistent problem. One would think twice before carrying important or sensitive data on portable media. If the pen drive is lost or compromised, sensitive data could fall in the wrong hands. But there’s a solution to this, password protection! You can simply password protect USB flash drives so that only you or authorized users can access the data. So there’s two types of protection, there’s simple password protection wherein data cannot be seen without entering a password and there’s encryption, in which the data is actually encrypted and can be decrypted and accessed only with a password. In the free tools below, we have both types of protection, so take your pick!

Top 5 Free Softwares to Password Protect a Pen drive:
