To answer my question... it works. I just plugged it in and it popped up under "Devices" in iTunes on my Mac. I remember initially doing it on a PC as well... so I'd assume it'll work there too. Looks like the database that was on there got killed somehow though... uppp... no it's back. I think the drive is dying though...

It's not showing the data that's on the Riot, and when I try and copy something over it says it contains an unformatted media module and asks if I want to format it. Might just be the drive dying though, it's clicking an awful lot.
