Strange Password Problem

[esehusey]

My problem is a little bit weird.

My son (very courious guy) demounted the hard disk of my S10-2. and remounted it. However, he faced with a blıue screen firs indicating this massage "Primary Master ################Lock" and request a password.

I have never faced such kind of password problem and could not find a relateed topic. Thus, anyone that could show me the way for solution will be greatly appriciated.

thanks
