Even new drives can crash if there was a problem within the manufacturing process. They have been tested and tested again before delivery to the store but defects do get through the testing programs. If you happen to have more than one drive on your PC, that would be nice and would make the copy process easier. Just select all the files you need and copy them into a temporary folder where you can retrieve them later in the other drive once it is set up to boot as the primary drive. The primary or master drive is the one that has the operating system installed onto it which in many cases would be Windows.
