Also suffering this UI bug of sort, also on Ubuntu 12.10. On my machine, four of the eight partitions are displayed with a star.
The right-pointer triangle appears when the partition is mounted, so it's probably meant as a "media play" metaphor. The star usually means "new" (irrelevant here), or "preferred" (also irrelevant here). It's not correlated with the filesystem type of the partition. It's most probably a feature, but certainly fails most reasonable human interface guidelines. For example, Gnome guidelines about tool bars ( https://developer.gnome.org/hig-book/3.0/toolbars-labels- tooltips.html.en ) mention: > Every control that appears on your toolbar should have a tooltip, whether or not that control has an associated text label. The tooltip should be a concise description of the control, but should provide more information than its text label where possible. For example, Open an existing document, or Undo last operation. About icons ( https://developer.gnome.org/hig-book/stable/icons.html.en ): > Icons are a graphical metaphor presenting a visual image that the user associates with a particular object, state or operation. When a user sees a good icon they are immediately reminded of the item it represents, whether that be an application in the panel menu or the "right aligned" state in a word processor toolbar. These star and triangle icons in gnome-disks fail at these sentences.

These icons are unlabeled, do not have hover text, are not self- explanatory, and do not appear to respond to left or right mouse clicks. Furthermore, there is no sign of a Help menu within the Disks window or application menu. I have no idea what these icons mean.
