One of the things you want to do, you really have to do, when you have computers, is backing up the data to a repository you can trust.
Right now, that's a big external hard-drive.
Fire up the command-line, and cp -auv * //media/removable/WD6, and just let it go...
Except, I forgot how many flash-drives I've acquired over the years.
And because I'm paranoid about data, I always copy something on each one.
This is going to take a while.
