The story can't be verified and doesn't really make much of a difference since the OP is not selling anything. So might as well relax and go along with it. I'm still hoping to find out how the drive was attached to the wall and what tools it was supposed to hold.
The point also was that since it's a made up story, the "nailed" part and the use of that could also be made up (and may not be realistic enough).
But I won't interfere more.
