DS_Store just includes basic window configuration information for Macs. Stuff like list vs icons, size of the columns, etc, so you have a consistent UI look when you're accessing your remote drives. It can be toggled to avoid it on removable devices when they're connected to Macs. It's benign, though I guess annoying to some non-Mac users.
