Seagate Free Agent Go

[Alexwithad]

I'm using a Seagate Free Agent Go for my Macbook to hold all my music & movies. (Legally downloaded :cool:) But I wanted to know if there was a way for it to sync automatically? For example yesterday I put my 20 gig of music on there and today I downloaded a few new songs, will I have to manually copy those over or is there a way i can set it to sync?

Thanks!
