We have come a long way since the days of floppy disks when it comes with external storage. These days you are more than likely to use a USB flash drive as your primary portable storage solution.
Also known as pen or thumb drives, USB flash devices are compact, easy-to-use, and seemingly universal storage devices. You can stick them into any computer to view their contents. However, if you store sensitive data on your flash drive, you should considering using password protection on the data or the device to prevent unauthorized access.
You can encrypt and protect your data on the flash drive with encryption software or you can get a special encrypted drive with the encryption tools embedded right into the drive.
If you only have a generic drive and do not want to buy a new flash drive right away, you can choose the first option. There are several encryption programs out there, and most flash drives sold in the last ten years come with their preferred solution already on them. You just have to install it. Though for this blog post, we will use the open source TrueCrypt disk encryption software.
You will need the following items to install the encryption software and to protect your flash drive data.
A computer with the Windows® operating system
A working USB port
