my friend's external HDD turned its data into RAW data. After googling what to do with it, I've found TestDisk utility to be quite good for such problem.
I proceeded as the documentation says and because I was unable to use chkdsk, due to RAW data error, I stepped onto repairing boot sector. I've gotten to this point after rebuldingBS, shown on the screenshot

Here, I am not sure what to do, since these messages made me uncertain. I can see most of the files in "List" (some of them are displayed red, which I don't know what that means). Should I backup BS, despite those messages above, or should I quit the process and do something else?
