BluePlayer

I am using external drive 320 GBs large and sometimes it gets unresponsive, which means I need to unplug it and then plug it again in order to use it. That means two scans each of them lasting at least hour and a half. Is there a way to save scan report and browse it even if I have my disk unplugged from the computer?

I have lot of PDF files and while I can restore them by using tree view, I need to search it manually. Is there some option or command line tool that can restore only PDF files automatically? For example like a command with params I can send?
