I understand, my drive up and went missing as well. As for the device manager, I've already tried that road and it's not even showing I had a drive to begin with. The only place I am seeing my drive is the system info "history" which, as far as I can tell, is unable to be altered.

If someone could perhaps lead me in the right direction?
I really don't want to drag the 'puter out and open it up. I just rearranged the whole space.

Cheers!
