You should probably not keep using your 10 gig along with your soon-to-be-purchased 80 gig. When you swap out the 10 gig for the next 80 gig, you'll loose that 10 gig worth of music. And the empeg doesn't put specific songs on specific drives, so you'll probably loose half of every playlist when the 10 gig comes out. At least, that's how I understand it

Have you done a hard drive upgrade? As part of the process, he can transfer the music from his 10GB to his new 80GB. The tutorial explains how to either add a 2nd drive or replace one of your existing drives. Replacing a drive involves copying the music.
