I just tried to copy about 200 images from my card, and had about 10 that just wouldn't copy (after i got some off by removing and reinserting the card reader). I was going to try copying directly from the card, but then I found this at another forum--the "parameter is incorrect" topic is on hundreds of forums regarding many different memory sources, so it must be a common thing (probably just on PC's...). Anyway, this worked like a charm for me:
Quote: I solved this problem after a good while tweaking around. If you still have the picture files stuck in the card, open up Windows Explorer. Highlight them and go to Properties (right click mouse button), and see if the "Archive" box is checked or unchecked. Mine were checked. When I unchecked them, I was able to transfer to my PC without any errors. I think it Archive mode was a safety mechanism to prevent corrupting the files when interruptions such as shutting off the camera while it was still working.
