I filed http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=203248for FC5. My drive is a Cyberdrive CW038D (they're currently being sold for $17.99 with free shipping at pcdirect.com - too bad they don't work properly). It seems to affect all of Cyberdrive's models. Above I should have written "_Attempting_ a full blank" - neither kind of blank actually works.
