Here's what I would do . . .
1. Backup your stuff, just because you should.
2. Use your 55.9GB 'slave' drive as your storage drive and copy all your stuff to it. Sort it and make it look neat.
3. Format the 14.3GB 'master' drive and use it just for your WINDOWS install. I don't know what other software you run, but that 14.3GB should be more than enough to run WINDOWS and some applications. If you're into gaming, you may need to consider installing your games to your 55GB drive.
4. Rejoice in the fact that you have a clean install and have separated your OS and DATA so that if you ever have to reinstall again, you'll know your DATA is safe on another drive.
5. And I forgot to mention, get rid of that Norton crap.
