Apparently, System X (I have upgraded to 10.4.11) can recognize PC diskettes, but only Mac diskettes created under System 9.2 and above. Older Mac diskettes or blank diskettes, whether PC or Mac, are invisible to the System X Finder even when the diskettes themselves are intact, as I can confirm under System 9.1. Before setting out to restore old files, I perhaps should have been aware of this limitation of System X, but Apple, I believe, was less than forthcoming in its utilities, alerts, tech notes, and telephone support, none of which were of much assistance.
