How to encrypt data on an external hard drive?
This is my problem, I'm a student and I live with two roommates. When I go to school, I carry my external HDD with me for protection, because I'm scared that they will copy everything from the HDD when I'm not around to see it. So I googled and saw that encryption is the only way to secure with password, but I'm scared to try why I think that it will delete all my data. The external hard drive is Apacer AC202 SATA External Hard Drive. With it comes a backup software that makes invisible partition so no one can see it, but again, I'm scared to try. So please help me to understand encryption more clearly, step by step (it will be more helpful with pictures or video). Please share other options for securing the HDD to.
Thanks in advance.
