So I was playing around with disk mode on the iPod at work this afternoon at work. Plugged in the iPod. Found the disk, even though it took like 3 minutes. I started browsing around the file system. Under \iPod_control\ there is a directory called Music and under that is a file structure from F00 - Fxx. I copied a file over to the local hard drive, disconnected the iPod, and tried playing the music. No problems at all. I thought Apple designed the iPod so you couldn't copy music from the device without external "tools".
