I have to password-protect two folders: folder A is on my computer's hard drive, and folder B is on an external hard drive.
Regarding folder A: I have tried encrypting folder A using Cryptkeeper but, after doing so, the system does not allow me to unmount folder A because "you are not root", which I actually am.
Regarding folder B: I have tried using Cryptkeeper similarly to above, but the same error message popped up.
Could you suggest a way of password-protecting folders A and B? Any guidance will be very much appreciated.
