Is there a way to refresh "all" movies?

I had a big mess the other day. I had three of my 1 TB drives die. Have 2 4 TB, a 3 TB on the way, a 3 in the machine and a 1 in the machine. Plenty of storage space still... Had to format a c drive though.and in doing so I lost all the metadata of movies. Now for the question. The data for the movies will load however I have to "refresh" it to make it load. Is there a way I can make it load without having to do this and if so how? About 20 percent of the movies did load automatically but when you have a lot of movies 20 percent is nothing!
Thanks,
