Yep. I can understand why one of the bosses was anxious about reformatting the laptop to me before handing it over. There is risk of giving away sensitive data if you are handing over or selling your PC or laptop. The boss probably does not know how to erase hard drive, just like me, and that is possible not leaving a trace of those sensitive data that can be read and recovered still.
I do not know that either. What I and the others know is if you reformat a PC unit, you erase everything. Well, I was ignorant, that I have to accept. It is interesting to learn though that there is a tool that could do drive-wiping. How I wish I had learned of this earlier. 🙂
