I've just set my Commodore 64 system back up all nice-like, and I'm having trouble. I've got a CMD 3.5" floppy drive for it, and the one disk I need to make it work (fd-2000 utilities disk) has errors out the wazoo. Looking at the magnetic disk itself, it's fairly mucked up. Little tiny micro ferns growing all over it. I've had some success in the past cleaning Amiga disks back to life using rubbing alcohol and a flannel cloth, but it just ain't working here. Anybody have a magic elixir that they use for such a task, or am I blue'd and tattoo'd on this one?
