In any case what is in your photos that you don't want anybody to see. I'm sure the repair guys has no interest, nor time to be looking at people photos or files. What could he possible do with them.
Passwords can be use for individual files which I have used, and folders (I think)
Thanks again everyone. I downloaded Truecrypt and did the encrypted file part rather than the partition. I then bunged everything into it so everything is protected and only I and wife know the password.
