I’m about to update my PC (motherboard, RAM and processor) and I don’t want my technician to look at my private files while my hard drive (and the rest of the PC) is with him. So, I’m looking for a way to password protect a folder from my drive so that he can’t enter. I will need to unlock it (make it a normal folder again) when I get my PC back (with new Windows, etc).
Is it possible to do the same with an external hard drive?
I read that many people recommend a program called TrueCrypt but I don’t know if it can full-fill my needs.
