I need help backing up my games

Hello everyone,
This is my first post so please bear with me. I have all of the sims 2 expansion packs. I want to back all of them up in case I lose any of them. I need to back up the core one too. All of mine are the north america versions because I live in chicago.
Here is a list of what I have:

The Sims 2 Holiday Edition from 2005
The Sims 2
The Sims 2 University
The Sims 2 Nightlife
The Sims 2 Open For Business
The Sims 2 Pets
The Sims 2 Seasons
The Sims 2 Family Fun Stuff
The Sims 2 Glamour Life Stuff
The Sims 2 Happy Holiday Stuff
The Sims 2 H&M Fashion Stuff

Please help me! When I tried to copy one of them it said ‘‘read examination error’’ I have the newest version of alcohol. And I have Windows XP

The read errors are normal. Just set the Safedisc 2/3/4 profile and let them finish.
