It is easy to lose USB flash drives or external hard disk drives. When you encrypt a drive, the content can be read only after the correct password has been entered.
1 Encrypting a USB stick
The open source tool DiskCryptor can encrypt complete drives. For this, right-click the USB stick in DiskCryptor, select “Encrypt” and assign a strong password – the best option would be an entire sentence with spaces, numbers and symbols.
2 Using secured disks
Ignore Windows’ suggestion to format the disk. Start DiskCryptor, click the disk and then “Mount”. Now use the drive as usual. Before pulling it out, don’t forget to click on “Unmount”.
3 Reproducing TrueCrypt containers
Open the Windows Disk Management (press [Win] + [R] and enter “diskmgmt.msc”, [Enter]) and click “Action | Create VHD (Virtual Hard Disk”. Select the storage destination and size. In the disk management, right-click the new disk and initialise it (MBR). Create a new volume that you will code with DiskCryptor just like a USB stick.
