Here is an article on using the Takeown command-line interface to take ownership of your D drive: http://www.winhelponline.com/blog/take-ownership-of-file-or-folder/
Here is a review article on 18 Free
Data Recovery Software Tools: https://www.lifewire.com/free-data-recovery-software-tools-2622893
And of these, the most well-regarded are as follows: Recuva, MiniTool Power Data Recovery
, and EaseUS Data Recovery Wizard
