If the latter, could be a batch fault. Try CF cards from different manufacturers. Remember though manufacturers may detect batch faults & not sell them, they may still be sold anyway ! Criminals exist & mislabelling happens. eg 2 tales: My family once had a number of USB sticks, 1 each, (2 Gig each costing 50 GBP (a lot of money, but not exorbitant then) at a Sunday computer market in UK), most were faulty with BSD & MS, I wondered if they might have been rejects from manufacturer, scheduled for destruction, & some criminal might have `rescued' them from the crusher, & sold them on.) A German magazine (CT) reported on placebo cache chips some years back, chips with pins but no silicon inside.
