Now thats one option that didn't come to mind !
Like others have said, I would suspect the card, reader, or the cable from the reader to the pc, having a fault or glitch.
Does it do it when the card is read straight from the camera?
Have you tried a different reader? Different PC?
I would try to eliminate the peripherals being faulty before assuming it was a bad batch of cards / the camera, since the readers and cables are usually the cheapest components.
