Take a pair of needle-nosed pliers and break away bits and pieces of the dork disc. It'll only take a few minutes.
Make sure your derailleur L limit screw is set properly. You don't want that chain jumping over the large cog and jamming between the cog and spokes. The dork disc prevents that from happening in case your derailleur is maladjusted.
